Refactor environment table titles and spacing

What does this MR do?

Refactors the environment table to take spacing and row titles from a single source of truth rather than scattered throughout the project. It does not change the look or functionality at all.

This is a part of the work done in !18115 (closed) that I have broken out to be its own MR.
