How to get rid of empty spaces in a QTableView based on QStandardItemModels, in yellow?

This is the code of headers:

mModel = new QStandardItemModel(0,6,this);
    mModel->setHeaderData(0, Qt::Horizontal, "Description", Qt::DisplayRole);
    mModel->setHeaderData(1, Qt::Horizontal, "Command", Qt::DisplayRole);
    mModel->setHeaderData(2, Qt::Horizontal, "Direction", Qt::DisplayRole);
    mModel->setHeaderData(3, Qt::Horizontal, "ACK", Qt::DisplayRole);
    mModel->setHeaderData(4, Qt::Horizontal, "ExpectedResult", Qt::DisplayRole);
    mModel->setHeaderData(5, Qt::Horizontal, "Result", Qt::DisplayRole);


       m_ui->Table_CSV->setModel(mModel);

m_ui->Table_CSV->horizontalHeader()->setSectionResizeMode(QHeaderView::Stretch);
m_ui->Table_CSV->verticalHeader()->setSectionResizeMode(QHeaderView::Stretch);
