QTableWidget::verticalScrollBar()->maximum() is always 0

[AnthonyL]

Overriding the maximum of a table view's scrollbar doesn't sound like a very good idea.
That value is usually determined by the table's data, i.e. how many rows it has an how high these rows are.

Yeah, but in my case, 1 out of 3 QTableWidgets doesn't have maximum() of verticalScrollBar updated. That's the point, the value is stuck at 0 despite insertRow() calls
