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
