Вызов контекстного меню правой кнопкой мыши для нескольких QTableWidget

У меня есть несколько таблиц QTableWidget, для каждой из них я хочу задать контекстное меню, которое будет вызываться по правой кнопки мыши.
В принцие уже нашел частное решение: Вызов контекстного меню по нажатию правой кнопки мыши на ячейку QTableWidget , но это реализация только для одной таблицы.

Чтобы не прописывать одно и то же для всех таблиц, попробовал пробежаться по списку существующих таблиц и создавать меню для всех, но застрял на моменте того, как передать переменную table в метод context():

            table.setContextMenuPolicy(QtCore.Qt.CustomContextMenu)
            table.customContextMenuRequested.connect(self.context(table)) #Как передать переменную table в context

В дополнение хотелось бы разобраться, откуда берется значение point в методе context из примера по ссылке. Заранее спасибо!
