Much easier is to override paintCell of QTable.

    def paintCell ( self, p, row, col, cr, selected):
        self.verticalHeader().setLabel(row, str(row *2))
        QTable.paintCell ( self, p, row, col, cr, selected, self.colorGroup())

The header will now be painted on demand....

My experience with PyQT is to pull the data from your data structures. Works 
much faster than iterating over objects.
