If I defined columns in a TableModel, but don't defined any row data, the HorizontalHeaderView which binds to a TableView via the syncView property, is not visible. I also tried a C++ model but it behaves the same.

Only after adding at least one row, the Header delegates get visible.

If I explicitly set the model to the HeaderView and don't bind via syncView, it gets visible.

I expected that the HeaderView is always visible, even when the model doesn't contain any rows. Or do I miss something?
