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.

For instance let we put an arrow from existing method images in first 
column:

   	aGrid column: 1
	  addBlock: [:rowObject | WebImage gif: #arrowCircledRedGif ]

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"

Best regards
Janko
