Aligning text in QHeaderView

[ShamusVW]

I have a QTableWidget with 2 columns, with a QHeaderView.
I left align all QTableWidgetItems in the left column, center align the right column QTableWidgetItems.
How do I now do this aligning of text to my QHeaderView? Currently both columns are center aligned, I want the first column header to be left aligned, the right column header to be center aligned.
This is my code for adding the QHeaderView in my class:

setRowCount(0);
    setColumnCount(2);
    setColumnWidth(0, 400); //set width of 1st column, 2nd column will auto-fit to remaining space
 
    QHeaderView *header = this->horizontalHeader();
    header->setSectionResizeMode(1, QHeaderView::Stretch); //let last column stretch to fit the table
    QStringList headerLabels;
    headerLabels << "Start of Stoppage" << "Duration";
    setHorizontalHeaderLabels(headerLabels);
    QFont *font	= new QFont("Helvetica",20);
    horizontalHeader()->setFont(*font);

setRowCount(0);
    setColumnCount(2);
    setColumnWidth(0, 400); //set width of 1st column, 2nd column will auto-fit to remaining space

    QHeaderView *header = this->horizontalHeader();
    header->setSectionResizeMode(1, QHeaderView::Stretch); //let last column stretch to fit the table
    QStringList headerLabels;
    headerLabels << "Start of Stoppage" << "Duration";
    setHorizontalHeaderLabels(headerLabels);
    QFont *font	= new QFont("Helvetica",20);
    horizontalHeader()->setFont(*font);

Thank you, I appreciate any help on this.

QTableWidgetItem * pItem = pTableWidget->horizontalHeaderItem( 0 );
pItem->setTextAlignment( Qt::AlignLeft | Qt::AlignVCenter );
 
pItem = pTableWidget->horizontalHeaderItem( 1 );
pItem->setTextAlignment( Qt::AlignHCenter | Qt::AlignVCenter );

QTableWidgetItem * pItem = pTableWidget->horizontalHeaderItem( 0 );
pItem->setTextAlignment( Qt::AlignLeft | Qt::AlignVCenter );

pItem = pTableWidget->horizontalHeaderItem( 1 );
pItem->setTextAlignment( Qt::AlignHCenter | Qt::AlignVCenter );
