I haven't done this in quite a while, but it
looks like you need to subclass QTableItem and
overload the paint method:

class CustomTableItem (QTableItem):
     def __init__ (self, table, et, text):
         QTableItem.__init__ (self, table, et, text)

     def paint (self, p, cg, cr, selected):
         if <some condition, like self.row () ==
            or something based on cell value>

             new_cg = <new QColorGroup defined by
                       your program somehow>
         else:
	    new_cg = cg

         QTableItem.paint (self, p, new_cg, cr, selected)

Each QTableItem holds row/col properties, so you
can use those to determine the row being painted.
(see QTableItem.row (), for example)

See the Qt docs for QTableItem::paint and QColorGroup.
There's also some example C++ code linked at
QTableItem.paint in the Qt docs.
