Apologies in advance if this has been discussed already; I lost track of
the list for a while.
That said, since updating to ELPA org-20170210, I can no longer (I'm pretty
sure this was working previously but I can't prove it -- maybe my document
was broken and I just didn't notice) use \columncolor{red} in the :align
argument to #+latex+attr: for tables any more; this gets changed to
\cocumncococ{ced} by the following ox-latex code:
3361 ;; Make sure cells are always centered while preserving
3362 ;; vertical separators.
3363 (let ((align (replace-regexp-in-string
3364 "[lr]" "c" (org-latex--align-string table
info))))
at
http://orgmode.org/w/org-mode.git?p=org-mode.git;a=blob;f=lisp/ox-latex.el;hb=9faf000e6a6977135a1d09dba4a078cdd9e04b38#l3361
I'm not certain whether I should be surprised that all non-centered
alignments are changed to centered, or that in general any text with an 'l'
or 'r' isn't valid in :align, or both.
This seems to have been commit 975260cb2596fb8cf0660cc91f2207c48b845699 to
preserve column groups, but I'm not sure I understand the original problem
or the fix. What does replacing l's and r's with c's achieve? Should I be
defining new column types and/or just using a \newcommand that doesn't use
the characters "l" or "r" instead of trying to directly set \columncolor
directly in the alignment string?
Thanks...
Phil

Can you please post an ECM (small example) of the org table with
attributes that you are having problems with?

See inline below and attached. If exporting to PDF the first table gets a
prefix of "ced!10" and the second is the pale red highlight I was wanting.
Here are the important lines in the LaTeX buffer export:
\(\left[\begin{array}{>{\cocumncococ{ced!10}}c|ccc|ccc}
vs.
\(\left[\begin{array}{a|ccc|ccc}
This latter only works because in my header I have
\newcolumntype{a}{>{\columncolor{red!10}}c}
I'm not sure I'm reading the original issue, the patch, or the surrounding
code right, but is it possible the [lr]->c substitution was intended for
the case where no :align was provided by the author and org generated the
alignment automatically? If so, would it be appropriate to just move the
substitution to the ";; Extract column groups and alignment ..." block in
org-latex--align-string, which is to say the case (if I'm reading
correctly) where the author has not provided an override?
ox-latex.el-3154-(defun org-latex--align-string (table info)
ox-latex.el-3155- "Return an appropriate LaTeX alignment string.
ox-latex.el-3156-TABLE is the considered table. INFO is a plist used as
ox-latex.el-3157-a communication channel."
ox-latex.el:3158: (or (org-export-read-attribute :attr_latex table :align)
ox-latex.el-3159- (let (align)
ox-latex.el-3160- ;; Extract column groups and alignment from first
(non-rule)
Org file to demonstrate problem and workaround:
#+latex_header: \usepackage{xcolor}
#+latex_header: \usepackage{colortbl}
* Non-Working Example
#+ATTR_LaTeX: :mode inline-math :environment array
#+attr_latex: :math-prefix \left[ :math-suffix \right]
#+attr_latex: :align >{\columncolor{red!10}}c|ccc|ccc
| | | * | * | | |
| * | | | * | | |
| \hline* | | | | * | |

Just define a column type that doesn't use the characters 'l' or 'r'
#+latex_header: \newcolumntype{a}{>{\columncolor{red!10}}c}
#+ATTR_LaTeX: :mode inline-math :environment array

Thanks for the example. I cannot add anything to your analysis. Hope
somebody else can help.
