void MainWindow::on_moveUp_clicked()
{
 
 QList<QTableWidgetItem *>   selection = ui.tableWidget->selectedItems();
 
 ui.tableWidget->selectionModel()->clear();
    int prev = -1;
 
    for( int i = selection.length() - 1; i >= 0; i -= 1 ) {
    int current = selection[i]->row();
    QTableWidgetItem *item;
 if( current != prev ) {
        item = ui.tableWidget->takeItem(current,0);
        QTableWidgetItem *itemBelow = ui.tableWidget->takeItem(current-1,0);
        ui.tableWidget->setItem(current,0,itemBelow);
        ui.tableWidget->setItem(current-1,0,item);
        prev = current;
        item->setSelected(selection[i]);
