Format datagrid row

[Quigster]

Hi,

I need to change the font color of the text in one specific cell in a datagrid. I've managed to change the font color of an entire column but I can't figure out how to reference a single cell. The nearest I've gotten is:

my_datagrid.getColumnAt(1).getItemAt(3).setStyle("color", 0x4E8F6D);

Does anyone know how to reference individual datagrid cells?

Thanks,
Quigster
