Thanks again Clay for all of your help.
I am now using your custom grouping engine, and it works quite well. Only three noticable issues:
(1) at some point as I am making a column narrower, the row height stops getting larger and text begins to get cut off (in the attachments, compare the 5th row in the top grid)
(2) once a row height has expanded to accomodate say 5 rows of text, the row height will never decrease again, even when I make the column width very wide. In other words, if the cell height has expanded to display 5 rows of text, then I make the column width very wide, and the text shrinks to only take up 3 rows, the row height is still tall enough for 5 rows.
(3) initially, in the lower grid, the row heights all come up perfect. But then, after adding a group, the summary column does not resize its height. (see the after.jpg file)
thanks!
