How to filter by parent/child relationship instead alphabetically?

Right now the index of tabular looks like this ->

See how it renders rows alphabetically but what I want to do is render rows by parent/child relationships.

I'm trying to structure the tabular index page like this ->

No files, tests, or entry points are named in the issue. Start by locating the tabular index rendering and its current alphabetical ordering, then determine how parent/child relationships are represented; done means the index renders rows in the requested hierarchy rather than alphabetically.
