I'm assuming you opened this PR to look for feedback, even though it's still a draft. I realize parts of it aren't ready for that yet, but I commented on them a couple times anyway, just in case. The table controller looks mostly good, although I haven't compared it to the functionality of the TPv1 counterpart. Obviously testing needs a lot of work.
I'm gonna try to work on migrating our tests to cypress over the holidays, which will hopefully make the e2e testing easier.

Yeah, I made it in draft because it's not ready for review yet. But thanks for your review, I'll check it. The code is copied from some other components and some parts I didn't change it ^^

@ocket8888 Can you take a look?

[ocket8888]

I do also still have to check the coverage; need to make sure it hits 100% in the modified files.

This method is not tested

Though it seems pedantic and trivial, testing this object's href method is the only thing preventing this file from having 100% coverage.
