You can prepare and put in a cell anything you want with:
aGrid column: aNumber addBlock: aBlock
Block is called with a current row object as argument and it must return a valid WebElement.
This is just what I was looking for! Is there anything you haven't thought of yet?
For instance let we put an arrow from existing method images in first column:
aGrid column: 1
addBlock: [:rowObject | WebImage gif: #arrowCircledRedGif ]
That will do it!
This can also be used for coloring cell content appropriately. But for coloring entire row you have some prepared methods too:
rowBlueIfTrue: [:rowObject | "some boolean expresion"]
rowGreenIfTrue:, rowRedIfTrue:, rowYellowIfTrue: rowGrayIfTrue:
rowBoldIfTrue: "for whole row to be bold"
Thank you...the WebGrid is truly useful. What did you think of my post last weekend about handling nil values in a sortable column? I just subclassed WebGrid for now, but it's nice to have the nil values sort without causing a DNU...
Thanks again.

P.S. I have registered for Smalltalk Solutions; I'll take good notes and share what I pick up!
