Bug: org-table latex export does not honour alignment [7.5]

Bug: org-table latex export does not honour alignment [7.5]

[Arik Mitschang]

When exporting a file to latex, the alignment of tables within that file
specified via the in-table <l>,<c> or <r> fields are not honoured. For
example:

|-------------+----------+----------+----------+----------|
|-------------+----------+----------+----------+----------|
| long header | header a | header b | header c | header d |
|-------------+----------+----------+----------+----------|
| <l>         | <l>      |      <r> |      <r> |      <r> |
| 1           | 2        |        3 |        4 |        5 |
| 6           | 7        |        8 |        9 |       10 |
| /           | >        |          |          |          |


should have the first two columns left-aligned and the last three right
aligned. The vertical line in the table above is present. This also is
the case when forcing a table environment via #+CAPTION. The table above
generates the tabular command:

\begin{tabular}{rr|rrr}

Where it should generate:

\begin{tabular}{ll|rrr}

Interestingly, when doing a

M-x org-table-export

The alignment is find, but the vertical line is present. Also, it
appears that ASCII also does not honour the alignment but HTML export
does (including the <c>).


Thanks,

You can specify the alignment for latex export directly if you put this
line before the table itself:

  #+attr_latex: align=ll|rrr

cf. (org) Tables in LaTeX export,

[[info:org#Tables%20in%20LaTeX%20export][info:org#Tables in LaTeX export]]

Hi Eric,

Thanks for the response. Yes, I'm aware of that, but it seems unnecessary when I
have already used the alignments in the table (and of course if you want HTML to
be the same alignment as latex then you would have to do both). I have a patch
that fixes this issue and behaves the same when alignment is not specified (or
is specified via the attr_latex). This patch is actually against org version
7.7. Not totally sure the best delivery method, but it is short so I include
here. Let me know what you think

Thanks,
-Arik

I'll leave this for others more capable in patching etc.!
