Worth noting that Emacs makes Markdown tables pretty easy to create and format cleanly for plain text viewing, and other editors may/could/should do the same.
I use Sublime almost 100% now-a-days; and, it for sure isn't as nice as Emacs for editing MD tables, but multi-cursor editing does about 80% of the heavy-lifting for MD tables. I guess I could conjecture someone objecting about "really big" tables and editing them ... but, is MD really the right choice in that case?
