Resizing QTableView inside a QTabWidget

Widgets outside layouts aren't resized automatically by their parent widget.
You have to set a layout (it doesn't matter which type) inside each tab of the QTabWidget too.

Thanks!!, this was the missing piece. I selected each tab and, using the context menu, set the layout to horizontal.. Now it works as expected.
