The recent developments on table’s usability in obsidian are amazing (late 2023).
There is a little thing I can suggest.
if you define by code the relative width of the tables by:
|C1|C2|C3|
|-|-|----|
it will be rewritten to:
|C1|C2|C3|
|----|----|----|
if you manage the table directly by the graphical editor.
Can it be integrated, so giving the possibility to fix relative width to the graphical editor ?
