Le tri de pyqt tablewidget

Comment puis-je trier un coloumn en pyqt par le plus grand nombre? Actuellement, j'ai setSortingEnabled(True) et que seuls les trie par la plupart des nombres (ex. 1,1,1,1,2,2,2,3,3) je veux le faire par le plus grand nombre par exemple (ex. 58,25,15,10). Merci!

Mise À Jour Des Données:

def setmydata(self):
    for n, key in enumerate(self.data):
        for m, item in enumerate(self.data[key]):
            newitem = QtGui.QTableWidgetItem(item)
            self.setItem(m, n, newitem)
