[flexcoders] How to change DataGridCell font color based on the cell value

[rzilist]

Hi folks,
I need to change the font color on my last DataGridColumn (not the 
ColumnHeader, just the cells) based on the cell value, i.e. if value 
in the cell is negative, change the cell font color to red. I've tried 
various HTMLRenderer classes, but to no avail. Please help!
Thanks,
Roman
