I'd really like to also take this opportunity to address some of the accessibility gaps in the table block, if you think that's possible.

Particularly:

#41502
#41014
#24205

@joedolson tjanks for flagging those. These Table block items will certainly be a stretch goal for me on top of my Editor Triage duties for 6.7. We’ll see! 🤞

Seeing that Beta 1 is next week (October 1), I think we should remove from the 6.7 board and punt this to 6.8.
