Trying to set numbers in a table but not working.

Hi!

I'm trying to show numbers in a QTableWidget, but my following code is showing nothing! There is no compile error. What's going on?

for(int i = 0; i < LINES; i++)
    {
        for(int j = 0; j < COLS; j++)
        {
            QTableWidgetItem val( QString::number( 123 ) );//This number is only for test.
            ui->tableWidget->setItem(i, j, &val);
        }
    }

for(int i = 0; i < LINES; i++)
    {
        for(int j = 0; j < COLS; j++)
        {
            QTableWidgetItem val( QString::number( 123 ) );//This number is only for test.
            ui->tableWidget->setItem(i, j, &val);
        }
    }
