(Apologies for sending this from gmail, my mail setup was not working
with the -Q option in emacs.)
A table in which a first column begins with square brackets is not
compiling. The square bracket is interpreted by latex as an argument
to the preceding line break.
Example org table:
| Input | Output |
|--------+--------|
| [1, 2] | {3, 4} |
| [5, 6] | null |
When exported to a PDF ( C-c C-e l o), I expect that the PDF to be rendered
with the brackets in the table as shown in org.
Instead, the result is a latex compilation error. The brackets are being
interpreted as length arguments to the preceding line break.
This is a relevant Stack Exchange issue (for pure latex) which suggests
some possible solutions.

with square bracket in table]]
To test, emacs was started with =emacs -q= to not load an init file.

I though that `concat' is better than `replace-regexp-in-string' or introducing two constants with/without newline. I guess, we can introduce the two constants. It might be slightly more optimal.

I had a hope that it is enough to introduce a single constant, but it seems it is not the case. I did not expect that newline should not be added e.g. planning export handler.

I applied the version 1 of the patch onto main changing the org-latex-linebreak-safe to org-latex-line-break-safe. https://git.savannah.gnu.org/cgit/emacs/org-mode.git/commit/?id=3f60acff7717e472d06833e9cf9fff6ca3d59337 Fixed. -- Ihor Radchenko // yantar92, Org mode contributor, Learn more about Org mode at <https://orgmode.org/>.
