Sorting Number Table Columns in PyQt4

Here is a simple trick to sort number columns in the QTableWidget of Qt4 and PyQt4: Format the number as a right aligned string:

for i range(12):
    item = QTableWidgetItem(u'%7d' random.randint(1, 10000))
    item.setTextAlignment(Qt.AlignRight)
    table.setItem (i, 1, item)
