DataGrid Component Column Header tooltips

Hi I am looking for a solution to complete within AS2 that allows a user to hover over a column header within a datagrid and a tooltip would pop-up.

I’m completeing a sports statistics sheet within Flash and I am obviously putting numbers in each column, else I would use the full column header but its just a number so I don’t want to increase the width of the columns just for that.

If anyone knows of a way to make each individual column header able to pop up a tooltip plz post or recommend something. To give an example if it isnt obvious of what I’m trying to do

Lets say my Table looks like so

GP | G | A | +/- | %

have a tooltip for each one of those pop up with a tooltip
