Perhaps you could simply return the desired sibling for the index returned by the base class implementation. Consider the following pseudo-example:

QModelIndex MyTableView::moveCursor(action, modifiers)
    QModelIndex index = QTableView::moveCursor(action, modifiers);
    if (action == MoveEnd && modifiers & Control)
        index = index.sibling(index.row(), currentIndex().column()); // keep the column intact
    return index;
