Hello org mode users!
I recently looked into getting org mode tables to properly align cell borders
and table border, when using Chinese characters in them.
I found out, that there is valign mode [1] and was happy with it for a few
days. But then I opened a document with lots of tables and some of those
tables bigger than what I had before in other documents. Scrolling inside that
document became quite laggy. So teeth-gnashingly I deactivated valign mode,
already suspecting it to be the culprit. And I was right. After deactivating
it, I could scroll perfectly fine again.
So I returned to the second alternative I had found out about, when searching
for a solution: Finding a font, which renders Chinese characters at exactly
double the width of latin/ASCII characters. I found a font named "Sarasa" [2]
and experimented a bit with setting the font globally, then setting it only
when opening an org mode buffer. Now it looks like that font does character
widths almost correctly (see attached screenshot, see slightly wider 4 ASCII
characters than 2 Chinese characters).
My settings for org mode regarding fonts/faces are:
~~~~
(add-hook 'org-mode-hook
(function
(lambda ()
;; Only do the following in graphical mode, as it will
;; break when using emacs in terminal mode.
(when (display-graphic-p)
;; Sarasa font is fromhttps://github.com/be5invis/Sarasa-Gothic.
(setq buffer-face-mode-face
'(:family "Sarasa Mono CL"
:weight normal
:height 110))
(buffer-face-mode)))))
~~~~
However, it seems, that now org mode does not align tables correctly, even
though an ASCII character is half the width of a Chinese character in the
tables. Org mode seems to add too few or too many spaces, which are displayed
as spaces of various width.—Is that because of the 1 pixel width difference?
Do I need to look for another font, which does things truly exactly, no 1
pixel too wide funny business? Maybe someone knows a more exact font?
Ultimately: How can I make tables align correctly?
My Emacs version is: GNU Emacs 28.2
My org mode version is: 9.6.1

I have tried something else today:
I looked at how the font is rendered in Libre Office. There it seems, that the
characters align perfectly (see attached screenshot). So maybe this is an Emacs
in general issue of font rendering, which adds a pixel to ASCII characters or
takes one away from CJK characters?
