Collapsed rows (in nested tables) remain in the DOM, but with style={display:none;}. This creates a nasty issue if someone is trying to stripe their table with even-odd CSS rules (which is very common).

Eg. https://table-react-component.vercel.app/demo/expanded-row-render

It seems like the fix would be to add the following to ExpandedRow:

if (!expanded) {
  return null;
}
