React Dynamic Data Table

This package provides a React Dynamic Data Table component that supports sortable columns, pagination, field mapping, data manipulation, and more.

Installation

You can install this package with either npm or yarn as shown below.

npm install @langleyfoxall/react-dynamic-data-table

yarn add @langleyfoxall/react-dynamic-data-table

Remember to import the DynamicDataTable component where it is needed.

import DynamicDataTable from "@langleyfoxall/react-dynamic-data-table";

Usage

At its most basic, you can create a new <DynamicDataTable /> with just the rows prop.

<DynamicDataTable rows={this.state.users} />

The rows prop expects an array of objects, such as the following.

[
  { name: "Picard", email: "[email protected]"  },
  { name: "Kirk",   email: "[email protected]"    },
  { name: "Sisko",  email: "[email protected]"   }
]

Excluding fields

By default, React Dynamic Data Table will render a table containing all fields present in the rows prop. To exclude specific fields, you can use the fieldsToExclude props.

In the example below, the email field will be excluded.

<DynamicDataTable
    rows={this.state.users}
    fieldsToExclude={['email']}
    />

In the example below, all ID fields will be excluded.

<DynamicDataTable
    rows={this.state.users}
    fieldsToExclude={[/_?id/]}
    />

The fieldsToExclude prop expects an array of strings or regex expressions that represent the fields to exclude.

Mapping fields

By default, React Dynamic Data Table creates table headers based on the field name, with underscores replaced with spaces and each word's first letter converted to uppercase. You can override this behaviour with a field map.

In the example below, you can render the email field as 'Email Address'.

<DynamicDataTable
    rows={this.state.users}
    fieldMap={{ email: 'Email address' }}
    />

The fieldMap prop expects an object which maps the rows keys to alternative field names.

Ordering data

The React Dynamic Data Table will display the rows in the order they are provided in the array. However, it is possible to show, in the column header, that the data has been sorted.

In the example below, the name column header will show a down arrow indicating that the data has been sorted by name (ascending).

// this.state.orderByField = 'name';
// this.state.orderByDirection = 'asc';

<DynamicDataTable
    rows={this.state.users}
    orderByField={this.state.orderByField}
    orderByDirection={this.state.orderByDirection}
    />

The orderByField prop expects a string indicating the field to sort by (one of the keys from the rows object).

The orderByDirection expects either asc or desc, meaning ascending or descending respectively.

If you wish to let the end-user sort the data table by clicking on the column headings, you can use the changeOrder prop. This is shown in the example below.

// this.state.orderByField = 'name';
// this.state.orderByDirection = 'asc';

<DynamicDataTable
    rows={this.state.users}
    orderByField={this.state.orderByField}
    orderByDirection={this.state.orderByDirection}
    changeOrder={(field, direction) => this.changeOrder(field, direction)}
    />

changeOrder(field, direction) {
    this.setState({ orderByField: field, orderByDirection: direction }, () => {
        const users = /* Get sorted data from API endpoint */
        this.setState({ users: users });
    });
}

The changeOrder prop expects a callable. This callable should:

1. Change the orderByField and orderByDirection props, based on the passed field and direction parameters respectively.
2. Change / re-retrieve the rows prop, such that it is sorted based on the passed field and direction parameters.

Ordering data is enabled for all fields by default. However, if you wish to restrict which fields the ordering is enabled for, pass an array of the field names into the allowOrderingBy prop. An example of this is shown below.

<AjaxDynamicDataTable
    rows={this.state.users}
    allowOrderingBy={[
        'name', 'email'
    ]}
/>

To have the opposite effect simply use disallowOrderingBy:

<AjaxDynamicDataTable
    rows={this.state.users}
    disallowOrderingBy={[
        'dob'
    ]}
/>

Typically, the allowOrderingBy and disallowdOrderingBy props should not be used simultaneously, as this could cause unexpected behaviour.

Ordering fields

By default fields will be ordered as they are passed into the table on each row. To force a specific ordering of columns an array of strings or regex can be passed with the fieldOrder prop. Anything that is not included within fieldOrder will be pushed to the end of the ordered fields.

<DynamicDataTable
    rows={[
        { id: 1, email: '[email protected]', name: 'Langley Foxall' }
    ]}
    fieldOrder={[
        'id', 'name'
    ]}
/>

// Output: id, name, email

Mixing strings and regex is also supported.

<DynamicDataTable
    rows={[
        { id: 1, email: '[email protected]', first_name: 'Langley', last_name: 'Foxall' }
    ]}
    fieldOrder={[
        'id', /_name/
    ]}
/>

// Output: id, first_name, last_name, email

Column Widths

In some cases there may be a need to make some columns be different widths by defining a width, rather than the table changing based off of content.

The columnWidths prop expects an object with column names as the keys and either a string or number as the values.

When a number is passed the width will become a percentage. If a string is passed then it respects whatever unit is set.

<DynamicDataTable
    rows={[
        { id: 1, email: '[email protected]', first_name: 'Langley', last_name: 'Foxall' }
    ]}
    columnWidths={{
        // 10%
        id: 10,

        // 100px
        email: '100px'
    }}
/>

Custom order by icons

When ordering by a field on an element will be rendered next to it. By default these are simple symbols (↓ and ↑). These can be changed by passing a valid node into orderByAscIcon and orderByDescIcon.

<DynamicDataTable
    orderByAscIcon="Ascending"
    // orderByAscIcon={<p>Ascending</p>}
    // orderByAscIcon={<FancyAscendingIcon />}
/>

Pagination

Making pagination work with React Dynamic Data Table requires three extra props. These are the currentPage, totalPages and changePage props. Once these props are set correctly, a Bootstrap style pagination will be displayed below the table.

The currentPage prop expects an integer representing the current page number (one or above).

The totalPages prop expects an integer representing the total number of pages in the data set (one or above). Pagination will only be shown if the total number of pages is greater than one.

The changePage props expect a callable with a page argument, indicating the new page number to load. This callable should:

1. Load a new page of data into the rows prop based on the passed page argument.
2. Set the currentPage prop to be equal to the passed page argument.

A example of this is shown below:

// this.state.currentPage = 1;
// this.state.totalPages = 5;

<DynamicDataTable
        rows={this.state.users}
        currentPage={this.state.currentPage}
        totalPages={this.state.totalPages}
        changePage={page => this.changePage(page)}
    />

changePage(page) {
    const users = /* Get page of data from API endpoint */
    this.setState({ users: users, currentPage: page });
}

Pagination is dynamic, showing only a select subset of the available pages as actual buttons. Whether or not an individual button to a page is shown depends on if it is the first or last page (these are always shown), and whether it is within a predefined offset from the current page (a pagination delta). This delta can be changed by passing a paginationDelta prop into DynamicDataTable as shown below:

<DynamicDataTable
        rows={this.state.users}
        currentPage={this.state.currentPage}
        totalPages={this.state.totalPages}
        paginationDelta={6}
    />

Per page limiting

Changing the number of entries displaying in the data table is easy. The totalRows, perPage, changePerPage and perPageRenderer allow you to customize a per page limit control.

• totalRows the total number of rows within the dataset
• perPage the current per page limit (default: 15)
• changePerPage handles the logic for changing the perPage prop. This recieved a single argument which is the new limit.
• perPageRender can either be a node or a function.

By default a Bootstrap styled select is displayed if changePerPage is a function.

<DynamicDataTable
    totalRows={totalRows}
    perPage={perPage}
    changePerPage={newPerPage => (
        this.setState({
            perPage: newPerPage
        })
    )}
    perPageRenderer={props => (
        <PerPage {...props} />
    )}
/>

perPageRenderer

The perPageRenderer prop accepts either a node or function. If a valid react element is passed then React.cloneElement is used to bind:

• totalRows
• value (see perPage above)
• onChange (see changePerPage above)

If a function is passed then the props described above are passed in an object.

Row buttons

Row buttons appear on the right hand side of every row in the React Dynamic Data Table. By default, a 'View' button is provided, which simply links the user to the current URL with the row's id appended.

You can completely override the row buttons that are displayed by provided a buttons prop. This prop expects an array of objects, each containing a name and callback.

The name is string, such as 'View', 'Edit', 'Delete', etc.

The callback is a callable with a two arguments. The first is the event object for the button clicked and the second is an object representing the current row.

An example of setting custom row buttons is shown below.

<DynamicDataTable
    rows={this.state.users}
    buttons={[
        {
            name: 'Edit',
            callback: (event, user) => {
                // Show edit user view...
            }
        },
        {
            name: 'Delete',
            callback: (event, user) => {
                // Delete user...
            }
        }
    ]}
    />

buttons can also be given a custom render at the top level, or for multiple array elements. It's worth noting that multiple array elements still respect the dropdown menu.

// Top level example
<DynamicDataTable
  buttons={row => (
    <a>
      <i className="fas fa-fw fa-eye" />
      <span>Totally custom button</span>
    </a>
  )}
/>

// Low level example
<DynamicDataTable
  buttons={[
    {
      render: row => (
        <a>
          <i className="fas fa-fw fa-eye" />
          <span>Totally custom button 1</span>
        </a>
      )
    },
    {
      render: row => (
        <a>
          <i className="fas fa-fw fa-tick" />
          <span>Totally custom button 2</span>
        </a>
      )
    }
  ]}
/>

Rendering custom rows

If you come across a situation where the automatically generated rows are not suitable for your project you can use the rowRenderer prop. This prop expects a callable that receives a single argument, and returns a valid React element, which should be a <tr> element.

The argument passed to the rowRenderer callable is a JavaScript object that contain the following properties.

{
  row,                // Instance of data row
  onClick,            // Row on click handler
  onMouseUp,          // Row on MouseUp handler
  onMouseDown,        // Row on MouseDown handler
  buttons,            // Array of buttons
  actions,            // Array of header actions
  fields,             // Visible fields
  renderCheckboxes,   // Boolean indicating whether to render checkboxes
  disableCheckbox,    // Boolean indicating whether to disable the checkbox per row
  checkboxIsChecked,  // Boolean indicating if checkbox is checked
  onCheckboxChange,   // Callable that is called when a per row checkbox is changed
  dataItemManipulator // Callable that handles manipulation of every item in the data row
}

For implementation details regarding these properties, see the other relevant areas of the documentation.

Clickable rows

Clickable rows allows an onClick prop to be passed. This should be a callable, that will be passed an event object along with an instance of the row that is clicked. It also adds the bootstrap table-hover class onto the table.

<DynamicDataTable
    rows={this.state.users}
    onClick={(event, row) => console.warn(event, row.name)}
/>

Mouse Events

For more complex interactions, such as supporting the ability to Middle-click, you can use the onMouseUp and onMouseDown events instead. It also adds the bootstrap table-hover class onto the table. The onMouseDown and onMouseUp props should be callables, that will be passed an event object along withan instance of the row that is clicked.

<DynamicDataTable
    rows={this.state.users}
    onMouseDown={this.handleMouseDown}
    onMouseUp={this.handleMouseUp}
/>

Context Menus

The ability to right click rows can be enabled by using onContextMenu and rowRenderer. In the example we will use our own @langleyfoxall/react-dynamic-context-menu:

<DynamicDataTable
    rows={this.state.users}
    rowRenderer={options => (
        <DynamicContextMenu
            key={options.key}
            data={options.row}
            menuItems={[
                {
                    label: 'Update',
                    onClick: this.handleUpdate,
                },
                {
                    label: 'Delete',
                    onClick: this.handleDelete,
                },
            ]}
        >
            {DynamicDataTable.rowRenderer(options)}
        </DynamicContextMenu>
    )}
/>

DynamicContextMenu clones the child and adds onContextMenu as a prop. This can also be achieved manually.

<DynamicDataTable
    rows={this.state.users}
    rowRenderer={({ row }) => (
        <tr onContextMenu={() => this.onContextMenu(row)}>
            <td/>
        </tr>
    )}
/>

Hoverable table rows

To enable a hover effect on rows even if onClick is not passed into the table you can use the prop hoverable. This will add a background color on each row when hovered.

<DynamicDataTable
    rows={this.state.users}
    hoverable
/>

Render no data component

If you wish to render something other than the table when no rows are present you can take advantage of noDataComponent which accepts a valid react element. This will replace the table until there are rows.

<DynamicDataTable
    row={[]}
    noDataComponent={(
        <p>I replace the table, not just the text inside it.</p>
    )}
/>

Bulk select checkboxes

If you wish to allow users to bulk select users in a React Dynamic Data Table, you can specify the renderCheckboxes prop. This will render a series of checkboxes against each row, on the left side of the table.

<DynamicDataTable
    rows={this.state.users}
    renderCheckboxes
    />

Bulk select checkboxes are usually combined with bulk actions to perform actions on one or more rows at once.

Disable checkboxes

Checkboxes can also be disabled for each individual row by passing in disabledCheckboxes which should container an array of identifiers. If an identifier is in the array then the checkbox will have disabled set to true.

<DynamicDataTable
    rows={this.state.users}
    renderCheckboxes
    disabledCheckboxes={[1]}
    />

Externally manage checkboxes

Combining isCheckboxChecked, onMasterCheckboxChange and onCheckboxChange allows a row's checkbox state to be managed outside of the datatable while still allowing disabledCheckboxes to work as intended.

In the example below, we are using a Set named checked to store the current status of the data table's checkboxes.

const checked = new Set

<DynamicDataTable
    isCheckboxChecked={({ id }) => checked.has(id)}
    onMasterCheckboxChange={(_, rows) => {
        let all = true

        rows.forEach(({ id }) => checked.has(id) || all = false)

        rows.forEach(({ id }) => {
            if (all) {
                checked.delete(id)
            } else if (!checked.has(id)) {
                checked.add(id)
            }
        })
    }}
    onCheckboxChange={(_, { id }) => {
        if (checked.has(id)) {
            checked.delete(id)
        } else {
            checked.add(id)
        }
    }}
/>

isCheckboxChecked

isCheckboxChecked is called on each re-render of the data table allowing for custom logic to determine if a checkbox is checked. It will receive the current row and the visible rows as arguments.

const checked = new Set

<DynamicDataTable
    isCheckboxChecked={({ id }) => checked.has(id)}
/>

Note: This should only be used if onMasterCheckboxChange and onCheckboxChange are implemented.

onMasterCheckboxChange

onMasterCheckboxChange is called when the master checkbox is clicked. This allows for custom logic for selecting and deselecting multiple rows. It will receive an event object from the input and the visible rows.

The master checkbox refers to the bulk select checkbox found in the top left corner of the data table whenever checkboxes are enabled.

const checked = new Set

<DynamicDataTable
    onMasterCheckboxChange={(_, rows) => {
        let all = true

        rows.forEach(({ id }) => checked.has(id) || all = false)

        rows.forEach(({ id }) => {
            if (all) {
                checked.delete(id)
            } else if (!checked.has(id)) {
                checked.add(id)
            }
        })
    }}
/>

renderMasterCheckbox

renderMasterCheckbox will determine if the master checkbox will be rendered

The master checkbox refers to the bulk select checkbox found in the top left corner of the data table whenever checkboxes are enabled.

<DynamicDataTable
    renderMasterCheckbox
/>

onCheckboxChange

onCheckboxChange is called when a row checkbox is clicked. This allows for custom logic for selecting and deselecting a single row. It will receive an event object from the input and the current row.

const checked = new Set

<DynamicDataTable
    onCheckboxChange={(_, { id }) => {
        if (checked.has(id)) {
            checked.delete(id)
        } else {
            checked.add(id)
        }
    }}
/>

Actions

Actions, when combined with bulk select checkboxes allow you perform actions of multiple rows at once. When in use, a menu will be rendered in the top right of the table allowing your users to choose a bulk action that will be applied to the selected rows.

Actions can also be used without bulk select checkboxes. This could allow for creation of action buttons that are not dependant on existing data, such as a 'Create User' button.

To use actions in your React Dynamic Data Table, you must specify the actions props. This prop expects an array of objects, each containing a name and callback.

The name is string, such as 'Delete user(s)', 'Duplicate user(s)' etc.

The callback is a callable with a single argument. The argument will contain an array of the selected rows.

Examples of how to use actions is shown below.

<DynamicDataTable
    rows={this.state.users}
    renderCheckboxes
    actions={[
        {
            name: 'Delete user(s)',
            callback: (rows) => {
                // Delete users...
            },
        },
    ]}
/>

<DynamicDataTable
    rows={this.state.users}
    actions={[
        {
            name: 'Create user',
            callback: () => {
                // Toggle create user modal...
            },
        },
    ]}
/>

Data Item Manipulation

If you wish to alter row data prior to it being rendered, you may use the dataItemManipulator prop available on the DynamicDataTable. This prop expects a function which will be passed three parameters, the field, the value and the row.

This function will be called once for every cell that is to be rendered.

<DynamicDataTable
    dataItemManipulator={(field, value, row) => {
        switch(field) {
            case 'id':
                return 'ID:' + value;
            case 'reference':
                return value.toUpperCase();
        }

        return value;
    }}
/>

It is also possible to render React components directly, by returning them from this function.

<DynamicDataTable
    dataItemManipulator={(field, value) => {
        switch(field) {
            case 'reference':
                return <ExampleComponent exampleProp={value} />;
        }

        return value;
    }}
/>

If you wish, you can dangerously render HTML directly by returning a string from the dataItemManipulator, you will however need to explicitly specify which fields this should be enabled for. This is done by using the dangerouslyRenderFields prop.

<DynamicDataTable
    dangerouslyRenderFields={['check']}
    dataItemManipulator={(field, value) => {
        switch(field) {
            case 'check':
                return "<i class='fa fa-check'></i>";
        }

        return value;
    }}
/>

Table footer

To display extra data at the bottom of the table a function or node can be passed into the React Dynamic Data Table by using the footer prop.

The footer is displayed directly in a tfoot to allow for multiple rows. So don't forget your trs.

Passing a function

When passing a function into the footer prop it receives an object with:

• rows: All of the visible rows
• width: The number of columns in the table

This should return a valid React element.

<DynamicDataTable
    footer={({ rows, width }) => (
        <tr>
            <td colSpan={width}>
                Table footer.
            <td>
        </tr>
    )}
/>

Passing a node

When passing a node or valid React element it is simply output.

<DynamicDataTable
    footer={(
        <tr>
            <td>
                Table footer.
            </td>
        </tr>
    )}
/>

Loading message & indicator

By default, the React Dynamic Data Table will not show indication that it is loading. On slow connections, this may make the table appear unresponsive or sluggish when initialing loading, changing pages, re-ordering, and so on.

To show a loading message, you can set the loading prop to true. This will display a default loading message, which can be changed by altering passing a string into the optional loadingMessage prop. If you wish, you can also pass a React component into the loadingIndicator prop, which will be displayed above the textual loading message.

<DynamicDataTable
    loading={true}
    loadingMessage="User data is now loading..."
    loadingIndicator={(
        <img src="/loading-animation.gif">
    )}
/>

Alternatively, if you wish to replace the entire table while data is being loaded, you can pass a React component into the loadingComponent prop.

<DynamicDataTable
    loading={true}
    loadingComponent={(
        <p>I replace the table, not just the text inside it.</p>
    )}
/>

To display either of these options loading must be set to true. Note that the AJAX Dynamic Data Table handles the loading prop internally but can be overriden.

Error message

In the case that something goes wrong, such as data failing to load, you can display and error message in place of the normal React Dynamic Data Table output.

In order to display an error message, you just need to set the optional errorMessage prop. This prop expects a string such as An error has occurred while loading user data.. If the error is resolved, this prop must be reset to an empty string in order to ensure the data table is displayed.

Editable Columns

If you wish to make certain columns editable you can specify how using the editableColumns prop. This prop accepts an array of object in the following format:

[
    {
        name: 'ExampleColumnText',
        controlled: false,
        type: 'text',
        onChange: (event, column, row, index) => console.log(event, column, row, index),
    },
    {
        name: 'ExampleColumnSelect',
        controlled: false,
        type: 'select',
        onChange: (event, column, row, index) => console.log(event, column, row, index),
        optionsForRow: (row, column) => [
            {
                label: 'One',
                value: 1
             },
            {
                label: 'Two',
                value: 2
            }
        ]
}]

Text Inputs

If you specify that the type of the column is text the column will contain a text input with a value of the column from the row data.

Selects

If you wish to use a select instead of a text input you may specify select as the type. The column will now contain a select input, by default with no options. In order to provide options implement the optionsForRow method. This method will be called with: The row data and Column name in that order. It should return an array of objects in this format:

[
    {
        label: 'Example one',
        value: 1
    },
    {
        label: 'Example two',
        value: 2
    }
]

Receiving input

In order to receive the users input you can provide the onChange method that will be called when the input is changed. This method will be called with the following parameters in the given order: The event from the input, The column name, The row data, The row index.

Controlled and Uncontrolled inputs

A uncontrolled input is an input whose value is controlled by the DOM. This means that it cannot be modified after the default value has been set by React. You will only receive input from the component and will not be able to modify the displayed value.

A controlled input will require you to store the value of the input in the state, the value of the input will be read from state meaning you will have to update state on user input to reflect it in component. In this case it will mean you will have to alter the data passed in as the rows prop.
