QT设置table居中

setTableAligCenter(QTableWidget *tw)

{

    int rowCount = tw->rowCount();

    int columCount = tw->columnCount();

    for(int row=0;row<rowCount;row++)

    {

        for(int colum=0;colum<columCount;colum++)

        {

            QTableWidgetItem* item = tw->item(row, colum);

            if(item != nullptr)

            {

                item->setTextAlignment(Qt::AlignCenter);

            }

        }

    }

}
