Remember that Python doesn't support methods with the same name but with 
different signatures - you have to handle this explicitly in code.

What you need to do is something like this...

	def paintCell(self, painter, row, col, rect, selected, cg = None):
		if cg:
			QTable.paintCell(self, painter, row, col, rect, selected, cg)
		else:
			QTable.paintCell(self, painter, row, col, rect, selected)
