The problem with this comes when deselecting rows. When you click an
already selected row a second time, it clears the selection, so
table.getSelection() returns null. There is no way to determine which row
was clicked on, so we don't know which to remove from the selection. You
can end route this by building the event listener in standard js. If
visual selection is all you need, then you can use CSS to highlight rows
(the viz API's built in classes provide easy access to this). If you need
to access data, then you'll need to do a bit more work to make sure the
rows selected in standard js match the ones you pull from the DataTable.
