I am still looking for a note editor that has good support for tables. Might as well use Excel for note-taking from now on.

How about Emacs + org-mode? Org-tables are plain text tables on steroids. You can quickly create, rearrange, modify these tables, and do even basic (or complex) calculations within them.

If its good or not can be discussed, but Obsidian supports tables. Obsidian also supports mermaid flowcharts. And there are plugins for mindmaps, GANTT charts etc. There really are an amazing range of functions in Obsidian.
