Emacs hangs opening org files with complex tables

[Addlai]

I'm a heavy user of tables in org mode. Some of the tables I use have org mode html links, which from a comment on the description page I think might be incompatible with valign.

In any case, I thought I should report that I had a problem using valign severe enough that Emacs would hang when visiting an org file with such tables. In some cases, I could partially recover by hitting ctrl-g enough times, but after this, Emacs would have very laggy behavior and did not display tables correctly. (No white space was added, so there was no column alignment.) In other cases, I had to resort to OS-level force-quit (this is macOS).

The fact that the problem was due to links in the table is just my guess. I haven't taken the time to investigate this carefully. I could try to produce a MWE if you think it would be helpful.

Hmm, usually large tables are skipped because of valign-max-table-size. Maybe your table are not large, but have something else that slows down parsing? It could really help if you can post some example.
