Show full contents on mouse over

If there is to much text in a particular cell, it overflows and displays the "..."

What my users want is when they mouse over, to show the full contents of the cell.

Something like a tooltip, but not exactly.

The popup should have the same formatting as the underlying cell. Its upper left hand corner should be located at the same place as the upper left hand corner of the underlying cell. And there should be no apparent impact on those cells that don't overflow.

Any ideas?

I could use something like this as well...

Why not just using the tooltip?

obj.setCellTooltip(function(c,r){return this.getCellText(c,r)});
