Looks like you have one on the contacts tab that isn't in a layout but
looks like it is. A spacer is useless outside of a layout.
A related problem I've noticed is that you aren't actually adding
everything to a layout. You have some layouts that don't have children (but
look like they're surrounding widgets).
Look in the Object Inspector tree for layouts without children (see video
where I remove a couple on the Contacts tab). You can see the difference in
resizing behavior when I get everything placed in layouts.

Double click on the table (see video).

There's a setting to stretch the last header sections (see video),
otherwise you'll have to do it in code (like through
table.horizontalHeader().setSectionResizeMode() )
