I haven't tried any of the community plugins - if any of them come close to what you want, why not file issues outlining what needs improving? I've only used Obsidian tangentially, but from 10000ft it does look like the app tends to incorporate the best plugin ideas over time, so this route might get what you want into the app eventually.
Emacs org-mode does demonstrate that it is possible to create a usable interface for text-mode tables.
