When using setSelectionModel of TableView

[IknowQT]

Using the frozen table view example, I am making a table view with fixed columns.

usrTableWidget::usrTableWidget(QWidget *parent)
	: m_pFrozenTable(new QTableView(this))
{
    Initialize();

    this->connect(
        this->m_pFrozenTable->verticalScrollBar(), &QAbstractSlider::valueChanged,
        this->verticalScrollBar(), &QAbstractSlider::setValue
    );
    
    this->connect(
        this->verticalScrollBar(), &QAbstractSlider::valueChanged,
        this->m_pFrozenTable->verticalScrollBar(), &QAbstractSlider::setValue
    );
}

void usrTableWidget::InitFrozenTableview(usrTableModel* pModel)
{
    //usrTableModel* pDataModel = qobject_cast<usrTableModel*>(this->model());
    //pModel->SetRowData(pDataModel->GetInputData());

    m_pFrozenTable->resizeColumnsToContents();
    m_pFrozenTable->verticalHeader()->setDefaultSectionSize(m_Size.height());

    m_pFrozenTable->setModel(pModel);
    m_pFrozenTable->setFocusPolicy(Qt::NoFocus);
    m_pFrozenTable->verticalHeader()->hide();
    m_pFrozenTable->horizontalHeader()->setSectionResizeMode(QHeaderView::Fixed);

    viewport()->stackUnder(m_pFrozenTable);
    
    m_pFrozenTable->setStyleSheet("QTableView { border: none;"
        "background-color: #8EDE21;"
        "selection-background-color: #999}"); //for demo purposes
    
    m_pFrozenTable->setSelectionModel(this->selectionModel());

    for (int col = 1; col < pModel->columnCount(); ++col)
        m_pFrozenTable->setColumnHidden(col, true);

    m_pFrozenTable->setColumnWidth(0, columnWidth(0));

    m_pFrozenTable->setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
    m_pFrozenTable->setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
    m_pFrozenTable->show();

    UpdateFrozenPosition();

    setHorizontalScrollMode(ScrollPerPixel);
    setVerticalScrollMode(ScrollPerPixel);
    m_pFrozenTable->setVerticalScrollMode(ScrollPerPixel);

    this->show();
}

m_pFrozenTable->setSelectionModel(this->selectionModel());
If you do not declare it, no data is displayed in the table view.

The initial screen of the table view should contain only data in the heat-fixed table. So in this->selectionModel() I get an error because Model doesn't exist.

I want to show only the heat setting data on the initial screen.
Is there no way?
