The selection event toggles the current selection. Maybe you want just the 'click' event instead.
I agree that being able to get the column index (or id even) when clicking on a table cell, and selecting a table cell, or whole column, would be a convenience for many applications. It will require some changes to the Table chart to support these, but I don't know of any inherent conflicts. Maybe I will get inspired over the next couple weeks.
