Subject: 11.89.5; Wrong indentation in tabular environment
Date: Tue, 20 Sep 2016 17:57:29 +0200

Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.

Be sure to consult the FAQ section in the manual before submitting
a bug report.  In addition check if the bug is reproducable with an
up-to-date version of AUCTeX.  So please upgrade to the version
available from http://www.gnu.org/software/auctex/ if your
installation is older than the one available from the web site.

If the bug is triggered by a specific (La)TeX file, you should try
to produce a minimal sample file showing the problem and include it
in your report.

Your report will be posted for the auctex package at the GNU bug
tracker.  Visit http://debbugs.gnu.org/cgi/pkgreport.cgi?pkg=auctex
to browse existing AUCTeX bugs.
------------------------------------------------------------------------

Consider the following 'my-init.el' file:
--8<---------------cut here---------------start------------->8---
(require 'package)
(setq package-load-list
      '(
	(auctex "11.89.5")
	)
      )
(package-initialize)
--8<---------------cut here---------------end--------------->8---

and the following 'test.tex' file:

--8<---------------cut here---------------start------------->8---
\documentclass{article}
\begin{document}
\begin{tabular}{l}
  \textbf{%
  Foo%
  }
\end{tabular}
\end{document}
--8<---------------cut here---------------end--------------->8---

Open them with:

--8<---------------cut here---------------start------------->8---
emacs -q my-init.el test.tex &
--8<---------------cut here---------------end--------------->8---

The '.tex' file is open with default emacs' TeX mode and its line "Foo"
can be indented as expected with TAB:

  ┌────
  │   \textbf{%
  │     Foo%
  │   }
  └────

Then, go to 'my-init.el' buffer and load AUCTeX with 'M-x
eval-buffer'. Now, go to 'test.tex' buffer and load "AUCTeX mode" on it
with 'M-x latex-mode': the "Foo" line is wrongly indented when TAB is
used on it:

  ┌────
  │   \textbf{%
  │   Foo%
  │   }
  └────

This bug doesn't arise if the 'tabular' environment is replaced by
another one, e.g. 'center'.

Hi Denis,

I cannot work on this right now, but I'm writing to acknowledge I can
reproduce the problem you reported.  I hope to be able to find some
time to look into it.

Bye,
Mosè

Quick follow-up.  Functions listed in `LaTeX-indent-environment-list'
should take care of the indentation in all possible cases.
Apparently, `LaTeX-indent-tabular' does not take care of all these
possible cases.  It could take advantage of
`LaTeX-indent-calculate-last'.  I'm sorry but I can't do this right
now, if someone is willing to dig further into this, please go ahead.

Bye,
Mosè
