`item->setFlags(item->flags() & (~Qt::ItemIsEditable));`

ui->tableWidget->verticalHeader()->setVisible(false); //隐藏垂直的序号
        ui->tableWidget->setColumnCount(2);
        ui->tableWidget->horizontalHeader()->setSectionResizeMode(QHeaderView::Stretch);
        ui->tableWidget->setRowCount(5);
        QStringList headLabels ;
        headLabels << tr("Column 0") << tr("Column 1") ;
        ui->tableWidget->setHorizontalHeaderLabels(headLabels);
        for(int i = 0; i < 5; i ++)
        { 
            QTableWidgetItem * item = new QTableWidgetItem();
            item->setText(QString("c0r%1").arg(i));
            item->setTextAlignment(Qt::AlignCenter);
            item->setFlags(item->flags() & (~Qt::ItemIsEditable));//设置不可编辑
            ui->tableWidget->setItem(i,0, item);
    
            QTableWidgetItem * item1 = new QTableWidgetItem();
            item1->setText(QString("c1r%1").arg(i));
            item1->setTextAlignment(Qt::AlignCenter);
            //item1->setFlags(item1->flags() & (~Qt::ItemIsEditable));
            ui->tableWidget->setItem(i,1, item1);
    
        }
