Задать названия вертикальным заголовкам в QSqlTableModel()

Возникла проблема с названиями вертикальных заголовков в QSqlTableModel(). С горизонтальными заголовками проблем никаких нет. С помощью метода setHeaderData() я задаю названия горизонтальным заголовкам, но с вертикальными это не получается (метод возвращает False). В интернете не могу найти ответ. Код:
