Qt Hide column in QTableView

问题:

I want to hide the ID column in the table view and i can't do that on my implementation. Can anyone help me?

void MainWindow::on_actionClear_Search_triggered() { model = new QStandardItemModel(cars.size(),6,this); //create header createHeader(model); //set data to the table view populate(cars);  ui->tableView->setColumnHidden(6,true); ui->tableView->setModel(model);   }  void MainWindow::createHeader(QStandardItemModel *model){   model->setHorizontalHeaderItem(0,new QStandardItem("Car")); model->setHorizontalHeaderItem(1, new QStandardItem("Type")); model->setHorizontalHeaderItem(2, new QStandardItem("Mileage")); model->setHorizontalHeaderItem(3, new QStandardItem("Year")); model->setHorizontalHeaderItem(4, new QStandardItem("Is registered")); model->setHorizontalHeaderItem(5, new QStandardItem("ID")); }  void MainWindow::populate(const QList<Vehicle> &vehicles) { int j = 0; QList<Vehicle>::ConstIterator iter; for( iter= vehicles.begin(); iter != vehicles.end(); iter++){     const Vehicle& car = *iter;     //set car     QString makeAndModel = car.getGeneralData().getMake() + car.getGeneralData().getModel();     QStandardItem *mAndM = new QStandardItem(QString(makeAndModel));     mAndM->setEditable(false);     model->setItem(j,0,mAndM);      //set type     QStandardItem *type = new QStandardItem(QString(car.getGeneralData().getType()));     type->setEditable(false);     model->setItem(j,1,type);      //set mileage     QString mileageString = QString::number(car.getGeneralData().getMileage());     QStandardItem *mileage = new QStandardItem(QString(mileageString));     mileage->setEditable(false);     model->setItem(j,2,mileage);      //set year     QString yearString = QString::number(car.getGeneralData().getYear());     QStandardItem *year = new QStandardItem(QString(yearString));     year->setEditable(false);     model->setItem(j,3,year);      //set registration     QString regString = VehicleHelper::convertBoolToString(car.getRegistration().isRegistered());     QStandardItem *regDate = new QStandardItem(QString(regString));     regDate->setEditable(false);     model->setItem(j,4,regDate);       //set ID column     QStandardItem *idNumber = new QStandardItem(QString(car.getVehicleID().getID()));     idNumber->setEditable(false);     model->setItem(j,5,idNumber);     j++; }  } 

回答1:

You use ui->tableView->setColumnHidden(6, true);, but there is no column with index 6. You should write ui->tableView->setColumnHidden(5, true); instead, because ID column number is rather 5 than 6.

UPDATE:

You also need to hide column(s) after you set the model to the view, i.e:

ui->tableView->setModel(model); ui->tableView->setColumnHidden(5, true);
