QStandardItemModel inside Qtableview

Question

I am using QStandardItemModel inside QTableView. Here i have two button & Qtableview inside my mainwindow. I need only 4 columns inside this. And rows will vary. The two Buttons will be used to add/delete a row (test case).

1. setHorizontalHeaderItem is not showing all the text(means all text is not visible). Example if i put 'Text for the Employee Name' it is not fully visible ?
2. How to make QStandardItemModel occupy full QTableview (width). At present it is showing at top left corner ?

How to achieve it?

Code :

model= new QStandardItemModel(4, 4);

    for (int row = 0; row < 4; ++row) {
        for (int column = 0; column < 4; ++column) {
            QStandardItem *item = new QStandardItem(QString("row %0, column %1").arg(row).arg(column));
            model->setItem(row, column, item);
        }
    }

    model->setHorizontalHeaderItem(0, new QStandardItem(tr("Time")));
    model->setHorizontalHeaderItem(1, new QStandardItem(tr("Text for the Employee Name")));
    model->setHorizontalHeaderItem(2, new QStandardItem(tr("Text for the Employee Address")));
    model->setHorizontalHeaderItem(3, new QStandardItem(tr("Text for the Employee Date of Birth")));

    model->setVerticalHeaderItem(0, new QStandardItem(tr("Test-Case-----1")));

Answer 1

tableView->horizontalHeader()->setStretchLastSection(true);

or

tableView->horizontalHeader()->setResizeMode(QHeaderView::Stretch);
