Proper fill for grid panel empty space beneath last row
I have a grid panel.
It displays a fixed number of items (though their height is somewhat variable).
The grid panel has a fixed height (tall enough that all items display...regardless of their height, with no scroll bar).
I'm using a row numbering column (first).
The problem is that there is a variable amount of white space between the bottom of the listed items and the page control.
Is there a reasonably simple way to get a cross browser friendly fill for the empty space that just looks like an empty row (first cell with the shading for a row numbering column etc.)?
A bodyCls doesn't seem to work...the row numbering fill is different depending on the browser (gradient for recent browsers, but solid for older ones).
I'm looking for suggestions to try.
