Hi all,

I am seeing a peculiar problem, and I would appreciate if somebody could check whether this is a bug or I am missing something.

The following table exports with a [0pt] at the end of each line.

* Test
| A | B | C |
|---+---+---|
| 1 | 2 | 3 |
|   |   |   |


\section{Test}
\label{sec:orgb720d02}
\begin{center}
\begin{tabular}{rrr}
A & B & C\\[0pt]
\hline
1 & 2 & 3\\[0pt]
 &  & \\[0pt]
\end{tabular}
\end{center}
\end{document}

I have tried this by running emacs -q (to check if something in my config was messing up). With emacs -q, my org-version is: Org mode version 9.6.7 (release_9.6.7-13-g99cc96)
​​​If I use my .emacs.d, my org-version is: Org mode version 9.7-pre (release_9.6.10-906-gee0961

Both give this strage [0pt] at the end of every line of the table.

​​​​​​Is this by design? This seems to be something recent. Am I missing something.

Thanks,

Vikas

I am seeing a peculiar problem, and I would appreciate if somebody could check whether this is a bug or I am missing something.

The following table exports with a [0pt] at the end of each line.I can confirm that the problem disappears if I move to the following version of org-mode:

commit bed47b437d8cde7a98bafdb07996e248b40f70e6 (HEAD -> main, origin/main)
Author: Rudolf Adamkovič <salutis@me.com>
Date:   Fri Oct 21 14:48:56 2022 +0200

Clearly, the problem has appeared more recently than this.

If you believe that it is a regression then try to export something like

| (a,b) | open interval   |
| [0,1] | closed interval |

If you believe that it is a regression then try to export something like

| (a,b) | open interval |
| [0,1] | closed interval |

https://list.orgmode.org/?q=%5B0pt%5D

 
I am sorry, but I do not understand what are you pointing at. This is what I get:

----
\begin{center}
\begin{tabular}{ll}
(a,b) & open interval\\[0pt]
[0,1] & closed interval\\[0pt]
\end{tabular}
\end{center}
\end{document}
----

What is this [0pt] at the end?

I think the point is that without the [0pt], the following line's [0,1]
gets interpreted as a length parameter for the line break, \\.

: Eric S Fraga, with org release_9.6.6-418-g294a4d in Emacs 30.0.50Earlier version gives me this:
\begin{center}
\begin{tabular}{ll}
(a,b) & open interval\\\empty
[0,1] & closed interval\\\empty
\end{tabular}
\end{center}
\end{document}

I have several export filters that break because of this [0pt]. For example, I use <mid> in a table row (created by an R source code) to mark wherever I want a midrule using this:

(defun org-export-midrule-filter-latex (row backend info)
  (replace-regexp-in-string "\\(<mid>\\([[:blank:]]+\\&\\)+\\)[[:blank:]]\\\\\\\\" "\\\\midrule" row))

Now my \midrule becomes \midrule[0pt].

It was changed to avoid your inconvenience:

That moment there was no hope that tabularray would support \empty out 
of the box. Perhaps some stable Linux distribution still have its 
version unaware of \empty.

Sorry, but your have to adjust the pattern and the replacement string to 
allow either optional \empty or [0pt].

I still do not see a better solution that does not require substantional 
changes of the org-export framework.

https://list.orgmode.org/874jw2conh.fsf@posteo.net/T/#uOh, wow! Thank you all for having been so considerate of needs of even individual users like this. I did not notice this.
Org mode community does not cease to amaze me.

Thank you once again.
