[PyQt] Complex header of QTableView

[Vadym Honcharuk]

Hello to List,

I created enought complex table based on QTableView (with models,
proxy, interconnections, etc) but now my task is similar complex
header for this table with miltiple rows, columns span and so on. As
far I know seems it's not trivial problem in Qt at all but perhaps I
wrong or exists roundabout ways, could you please share your recipes?

Thanks a lot!

With best regards,
