Change line 30 of mainwindow.cpp to

QStandardItemModel *model = new QStandardItemModel(5, 2);

QStandardItemModel *model = new QStandardItemModel(5, 2);

and the other lines accordingly.

Thanks very much! You saved my life

QStandardItemModel *model = new QStandardItemModel(5, 2);

QStandardItemModel *model = new QStandardItemModel(5, 2);
