C++ 寻址QTableWidget列

我是一名学生程序员，一直在为我的公司用Qt构建GUI。我正在编写一个成员函数SetData，基本上充当Ui元素和成员变量之间的中介。在这个特定的Ui中，我使用了一个QTableWidge。我似乎无法确切地找出如何将每一列设置为一个变量

例如，如果我的QTableWidget中有列名，而Name是第一列，那么我无法使用传统的数组参数访问它。关于如何解决这一问题，Qt提供的信息非常模糊。。也可能是因为我太业余了，无法理解如何使用类的成员函数来实现我想要的结果

为了澄清这一点，我试图为整个列定义一种数据类型。比如我的第一个专栏；Name是我创建的一个变量，它是一个QString数据类型。SetData最终会将其传递给QVector或QList。这是我到目前为止输入的代码，我想我可以做些什么

 void InjectionDialog::setData(InjectionData &setDataStruct)
    {
        /*The following setData functions assists in creating a new instance of
          the Injection dialog with whatever values are passed to setDataStruct*/
        QString str;//created str to make datatype conversion
        ui->lineEditFluidVelocity->setText(str.setNum(setDataStruct.lineEditFluidVelocity));
        ui->lineEditFluidMassFlow->setText(str.setNum(setDataStruct.lineEditFluidMassFlow));
    ui->lineEditFluidArea->setText(str.setNum(setDataStruct.lineEditFluidArea));
        ui->lineEditFluidTemperature->setText(str.setNum(setDataStruct.lineEditFluidTemperture));
        ui->lineEditFluidPressure->setText(str.setNum(setDataStruct.lineEditPressure));
        ui->lineEditParticleManual->setText(str.setNum(setDataStruct.lineEditManualParticlesPerCell));
        ui->lineEditParticleVelocity->setText(str.setNum(setDataStruct.lineEditParitcleVelocity));
        ui->lineEditParticleMassFlow->setText(str.setNum(setDataStruct.lineEditParticleMassFlow));
        ui->lineEditParticleArea->setText(str.setNum(setDataStruct.lineEditParticleArea));
        ui->lineEditParticleTemperature->setText(str.setNum(setDataStruct.lineEditParticleTemperture));
        ui->tableWidgetInjectionLocations //this is where I got stuck
}

我知道QTreeView可以通过委派列来设置项，但我需要这些字段才能编辑。在处理我的QTableWidget时，我可能会犯下所有错误；如果是这样的话，我非常感谢您对如何正确处理此小部件的建议。

通过QTableWidgetItem进行了一些研究和尝试；我找到了我要找的东西。如前所述，我需要编写一个setData函数，以提供一种使用QTableWidget将每个单元格设置为某些指定数据的方法。用于将每个项目设置为一个。知道了这一点，我只是填写了目的。这就是我所做的；这就在我的主代码之后

for(int i=0; i<setDataStruct.qTableWidegetlocations.size(); i++)
            {
                QTableWidgetItem *qTableWidgetItemInjectionName = new QTableWidgetItem(setDataStruct.qTableWidegetlocations[i].locationsInjectionName);
                ui->tableWidgetInjectionLocations->setItem(i,0, qTableWidgetItemInjectionName);
                QTableWidgetItem *qTableWidgetItemInjectionOnOff= new QTableWidgetItem((setDataStruct.qTableWidegetlocations[i].locationsInjectionOnOff));
                ui->tableWidgetInjectionLocations->setItem(i,1, qTableWidgetItemInjectionOnOff);
                QTableWidgetItem *qTableWidgetItemInjectionX = new QTableWidgetItem(setDataStruct.qTableWidegetlocations[i].locationsX);
                ui->tableWidgetInjectionLocations->setItem(i,2, qTableWidgetItemInjectionX);
                QTableWidgetItem *qTableWidgetItemInjectionY = new QTableWidgetItem(setDataStruct.qTableWidegetlocations[i].locationsY);
                ui->tableWidgetInjectionLocations->setItem(i,3, qTableWidgetItemInjectionY);
                QTableWidgetItem *qTableWidgetItemInjectionZ = new QTableWidgetItem(setDataStruct.qTableWidegetlocations[i].locationsZ);
                ui->tableWidgetInjectionLocations->setItem(i,4,qTableWidgetItemInjectionZ);
                QTableWidgetItem *qTableWidgetItemInjectionnx = new QTableWidgetItem(setDataStruct.qTableWidegetlocations[i].locationsnx);
                ui->tableWidgetInjectionLocations->setItem(i,5,qTableWidgetItemInjectionnx);
                QTableWidgetItem *qTableWidgetItemInjectionny = new QTableWidgetItem(setDataStruct.qTableWidegetlocations[i].locationsny);
                ui->tableWidgetInjectionLocations->setItem(i,6,qTableWidgetItemInjectionny);
                QTableWidgetItem *qTableWidgetItemInjectionnz = new QTableWidgetItem(setDataStruct.qTableWidegetlocations[i].locationsnz);
                ui->tableWidgetInjectionLocations->setItem(i,7,qTableWidgetItemInjectionnz);
                QTableWidgetItem *qTableWidgetItemInjectionTemperature = new QTableWidgetItem(setDataStruct.qTableWidegetlocations[i].locationsTemperature);
                ui->tableWidgetInjectionLocations->setItem(i,8,qTableWidgetItemInjectionTemperature);
                QTableWidgetItem *qTableWidgetItemInjectionWeight = new QTableWidgetItem(setDataStruct.qTableWidegetlocations[i].locationsWeight);
        }

for（int i=0；itableWidgetInjectionLocations->setItem（i，0，qTableWidgetItemInjectionName）；
QTableWidgetItem*qtableWidgetItemInjectionNoff=新的QTableWidgetItem（（setDataStruct.qtableWidgetLocations[i].LocationsInjectionNoff））；
ui->tableWidgetInjectionLocations->setItem（i，1，qTableWidgetItemInjectionNoff）；
QTableWidgetItem*qTableWidgetItemInjectionX=新的QTableWidgetItem（setDataStruct.qtableWidgetLocations[i].locationsX）；
ui->tableWidgetInjectionLocations->setItem（i，2，qTableWidgetItemInjectionX）；
QTableWidgetItem*qTableWidgetItemInjectionY=新的QTableWidgetItem（setDataStruct.qtableWidgetLocations[i].locationsY）；
ui->tableWidgetInjectionLocations->setItem（i，3，qTableWidgetItemInjectionY）；
QTableWidgetItem*qTableWidgetItemInjectionZ=新的QTableWidgetItem（setDataStruct.qtableWidgetLocations[i].locationsZ）；
ui->tableWidgetInjectionLocations->setItem（i，4，qTableWidgetItemInjectionZ）；
QTableWidgetItem*qTableWidgetItemInjectionnx=新的QTableWidgetItem（setDataStruct.qtableWidgetLocations[i].locationsnx）；
ui->tableWidgetInjectionLocations->setItem（i，5，qTableWidgetItemInjectionnx）；
QTableWidgetItem*qTableWidgetItemInjectionny=新的QTableWidgetItem（setDataStruct.qtableWidgetLocations[i].locationsny）；
ui->tableWidgetInjectionLocations->setItem（i，6，qTableWidgetItemInjectionny）；
QTableWidgetItem*qTableWidgetItemInjectionnz=新的QTableWidgetItem（setDataStruct.qtableWidgetLocations[i].locationsnz）；
ui->tableWidgetInjectionLocations->setItem（i，7，qTableWidgetItemInjectionnz）；
QTableWidgetItem*qTableWidgetItemInjectionTemperature=新的QTableWidgetItem（setDataStruct.qtableWidgetLocations[i].locationsTemperature）；
ui->tableWidgetInjectionLocations->setItem（i，8，qTableWidgetItemInjectionTemperature）；
QTableWidgetItem*qTableWidgetItemInjectionWeight=新的QTableWidgetItem（setDataStruct.qtableWidgetLocations[i].LocationsWight）；
}

QTableWidgetItem*newItem=new QTableWidgetItem（tr（“%1”）.arg（（行+1）*（列+1））；tableWidget->setItem（行，列，新项）；该文档中的这段代码是否有什么不能为您做的？
