Fix Scrolling lag on Dataset Schema Tables

[AlexxRosaa]

Fix scroll lag on dataset schema tables

Navigating to a "Dataset" and viewing the table under the "Schema" tab will sometimes cause scroll wheel lag or auto movement when there are over a certain amount of schema fields that are being rendered.

Change

• If the number of rows is under 40 the scroll wheel will remain, otherwise, there is a check added to see if there are over 40 rows to remove the scroll wheel entirely to prevent lag and render all fields at once
