Enhancing TG trigger, runtime progress, etc

[AARON-CLARK]

@Jeff-Thompson12, what do you think about the prospect of adding a progress bar the the table generator? Obviously in a different PR.

I think we might want to go even farther and think about when table generation should be triggered and what UI elements we want the user to be able to interact with while a table is being generated.
