thing will break. The real solution for this would be to
switch to a programmed solution instead of a regular
expression search.
Or many regular expressions, one for each context: table, heading,
comment, text, …
Based on the context, you choose one or another. To know the
context, there may be some text property set at each point.
If Emacs had a way to check for a text property (or even a face)
inside a regexp, this could be easier. You could still use a single
expression which would direct to the context-specific part, like
in: \p{heading}REGEXP_ONLY_FOR_HEADINGS\|\p{table}REGEXP_FOR_TABLES
\|… where \p{property} is the proposed addition to Emacs regexps.
All we would really need are positive and negative look-ahead
and look-behind assertions as the Perl regular expression allows them.
