Tooltips on Perspective table columns/cells?

Tooltips aren't available for rows/columns/cells of tables.

There are a few ways people have done it with mouseOver event and x,y positions, but I think they break down when the scroll bar is active and not at the top.

If the powers at be are wanting more description on the columns, you could implement a label somewhere that changes text and use the prop.selection property to determine the row/column that is selected to change that label.
