qml TableView top left corner

[majorRonk]

How do you normally show the corner in the top left of the TableView
when both horizontal and vertical headers are visible and you don't want to have a blank space there?

I could move the anchor of horizontal or vertical HeaderView and add an additional empty headerdata for the first element,
but it looks a bit weird.

The QTableView class has cornerButtonEnabled attribute. I couldn't anything in qml which handles the corner.
