Сохранение данных QTableView при закрытии приложения с использованием QSettings

Изъезженный вопрос но тем не менее до сих пор не могу понять как сохранить данные после закрытия. Использую QtCore.QSettings(). Написал часть кода для сохранения, не работает.

• сюда же отдельный вопрос как расширить колоны в таблице в коде?
