copy table to Excel

[Arend]

Hello,

I am a absolute beginner and I can't figure out how to copy a simple table to Excel, see the code below.
Can someone help me out?

Regards,
Arend

MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow)
{
    ui->setupUi(this);
 
    QStandardItemModel *model = new QStandardItemModel(10,2,this);
 
    model->setHorizontalHeaderItem(0, new QStandardItem("Column_1"));
    for(size_t i=0;i<10;++i)
    {
        QModelIndex index = model -> index(i,0,QModelIndex());
        model->setData(index,QString::number(i+1,'f',0));
    }
    model->setHorizontalHeaderItem(1, new QStandardItem("Column_2"));
    for(size_t i=0;i<10;++i)
    {
        QModelIndex index = model -> index(i,1,QModelIndex());
        model->setData(index,QString::number((i+1)*(i+1),'f',0));
    }
    ui->tableView->setModel(model);
}

MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow)
{
    ui->setupUi(this);

    QStandardItemModel *model = new QStandardItemModel(10,2,this);

    model->setHorizontalHeaderItem(0, new QStandardItem("Column_1"));
    for(size_t i=0;i<10;++i)
    {
        QModelIndex index = model -> index(i,0,QModelIndex());
        model->setData(index,QString::number(i+1,'f',0));
    }
    model->setHorizontalHeaderItem(1, new QStandardItem("Column_2"));
    for(size_t i=0;i<10;++i)
    {
        QModelIndex index = model -> index(i,1,QModelIndex());
        model->setData(index,QString::number((i+1)*(i+1),'f',0));
    }
    ui->tableView->setModel(model);
}

To copy to clipboard, switch view to plain text mode
