Using internal links with aliases in a table will break the table rendering because the “|” defining the alias will be interpreted as “next cell”.
| column 1 | column 2 | column 3 |
|---|---|---|
| [[link | alias]] | text |
Is there a way to make the “|” divider in internal links compatible with the “|” divider in tables?
You have to escape it with \. So [title\|alias]
Indeed it works. So simple that it didn’t come to my mind 
Thank you
To me this feels like a bug. Obsidian could check that if there is [[ open when a | character appears in a table, the | character should be considered to relate to the [[ link element, and not to the table structure.
Escaping the | character seems like a workaround to me, not an actual solution 
. (But good that at least a workaround exists already).
These are just my opinions.
Block level elements take precedence over span elements, so table syntax is correctly processed before links.
