The core issue IMO is probably a failed justification of engineering cycles to help whiny users, who could actually help themselves.
Finally tried editing the full post ( NOT edit table ). And it’s fixed Chinese Wine — Ongoing Tasting Notes and Discussion - #10 by JamesMak.
Steps here:
- Create the table normally. Copy / Paste your own table. Hit Build Table. (This step is indeed less messy but you can go straight to type the markdown. )
- Once the table looks good. Go edit the post (hit the pencil icon at the bottom of the post, NOT the one top right of the table). The table markdown appears like below :
“|Column 1 |Column 2 |Column 3 |Column 4|”
“| — | — | — | — |”
“| | <your column name 2> | <your column name 3> | <your column name 4> |”
The markdown is without quotes, I put them to disable the table rendering here.
- Simply copy your own column name (3rd) row, paste it over the first row. Looks good, delete your own row.
p.s. I don’t know what caused the “your own columns” row to display like that. Looks right in the editor 
p.s. 2 Never seen what the admin sees, but that Discourse post is probably for dev. Not really helpful.
