Ahah, I found the tables! You have to go into Zim's settings and enable them as an addon in there. Ty, I thought there was no support whatsoever (other than putting pictures of tables in https://github.com/jaap-karssenberg/zim-wiki/wiki/Create-a-t... ).

Indeed it still seems a bit limited. Nothing like Firefox's in-built table editor used to be (this is the one in Thunderbird, which is quite nice). I wish they hadn't removed that feature :|

Treesheets is a beautiful program, but I'm too much of a pen-and-paper + plaintext notes person to appreciate it properly.
