在QTableWidget上添加框选，获取框选状态
添加选项框在表格中

	//添加选择框
    QTableWidgetItem* check0 = new QTableWidgetItem();
    check0->setCheckState(Qt::Checked);
    ui->tableWidget_TestResult->setItem(0, 0, check0);
    ui->tableWidget_TestResult->item(0, 0)->setTextAlignment(Qt::AlignHCenter | Qt::AlignVCenter);

	QTableWidgetItem* check1 = new QTableWidgetItem();
    check1->setCheckState(Qt::Checked);
    ui->tableWidget_TestResult->setItem(1, 0, check1);
    ui->tableWidget_TestResult->item(1, 0)->setTextAlignment(Qt::AlignHCenter | Qt::AlignVCenter);
    
	QTableWidgetItem* check2 = new QTableWidgetItem();
    check2->setCheckState(Qt::Checked);
    ui->tableWidget_TestResult->setItem(2, 0, check2);
    ui->tableWidget_TestResult->item(2, 0)->setTextAlignment(Qt::AlignHCenter | Qt::AlignVCenter);
    

获取框选状态：

	bool status1 = ui->tableWidget_TestResult->item(0, 0)->checkState();
    qDebug() << "message_updateTest1Status status" << status1;
    bool status2 = ui->tableWidget_TestResult->item(1, 0)->checkState();
    qDebug() << "message_updateTest2Status status" << status2;
    
    

在QTableWidget上更改颜色显示NG和OK
举例：设置

	int TestNum = ****;
    QString Eye  = ****;
    QString result = ****;
    int hang,lie;
    if (Eye == "LEFT")
        lie = 1;
    else if (Eye == "RIGHT")
    {
        lie = 2;
    }
    else
    {
        lie = 0;
        qDebug() << "haatData.data  Eye error!";
        return false;
    }

    QTableWidgetItem* item = new QTableWidgetItem();

    if (result == "OK")
    {
        item->setBackgroundColor(QColor(0, 255, 0));    //背景绿色
        item->setText("OK");
    }
    else
    {
        item->setBackgroundColor(QColor(255, 0, 0));    //背景红色
        item->setText("NG");
    }

    item->setTextColor(QColor(240, 248, 255));  //白色文字
    //item->setTextColor();
    ui->tableWidget_TestResult->setItem(TestNum-1, lie, item);
    ui->tableWidget_TestResult->item(TestNum-1, lie)->setTextAlignment(Qt::AlignHCenter | Qt::AlignVCenter);
