Qt so that each element in the middle (of the use of some qtablewidget) tableWidget content

First look at the effect of:

 

 　　// set the table style

    ui->tableWidget->verticalHeader()->hide();

    ui-> tableWidget-> horizontalHeader () -> setDefaultAlignment (Qt :: AlignHCenter); // header font center

    ui-> tableWidget-> setEditTriggers (QAbstractItemView :: NoEditTriggers); // cell is not editable

    ui-> tableWidget-> horizontalHeader () -> setStyleSheet ( "QHeaderView :: section {background: rgb (2,20,130); color: white;}"); // set the font color of the header

    ui-> tableWidget-> verticalHeader () -> setDefaultSectionSize (40); // set the row height

    ui-> tableWidget-> horizontalHeader () -> setStretchLastSection (true); // for each column sharing

    ui-> tableWidget-> horizontalHeader () -> setSectionResizeMode (QHeaderView :: Stretch); // column Scalable

    ui-> tableWidget-> setSelectionBehavior (QAbstractItemView :: SelectRows); // set the whole row is selected

     // so that each element tableWidget content centered

    for (int i=0;i<5;i++)

       {

           for (int j=0;j<8;j++)

           {

               ui->tableWidget->item(i,j)->setTextAlignment(Qt::AlignHCenter|Qt::AlignVCenter);

           }

       } 

One thing to note is that there are several odd row of data in the table, give i, j value assigned number, otherwise it will error "abnormal program end"
