I like how org-mode allows me to quickly create and edit tables. However, I do not like the table's appearance and I would like to modify it.
Customizing the face only lets me change foreground and background color. I want to change the grid only. The essence of this question was asked about 8 years ago here. Did anything change since then?
I also tried to solve this by font-locking the "|" (pipe/bar) character, however, it seems that my regular expression does not find it reliably and does not set the face.
(add-hook 'org-mode-hook (lambda () (font-lock-add-keywords 'org-mode '((" | " . 'font-lock-keyword-face)))))
So my question is: Can I hide the grid in org-mode tables?
