This guide shows you how to configure a tab in a window that uses a view (not table) as data source.
In general you create the view and table as described in here: Create window from database view.
But instead of a window you create a tab in an existing window.
In order to do that you need a link column between your view and the parent tab of the window you want to add your view to.
