Dear all, 

I have implemented tabbing (http://www.ctex.org/documents/latex/latex2e-html/ltx-58.html) support for ox-latex. By setting #+ATTR_LATEX: :mode tabbing
the exporter will use the tabbing environment. 

The benefits of using tabbing over tabular:
- Can span multiple pages (also possible with long tables).
- Cell width is fixed and does not depend on the content.
- Cells can overflow. 

Use cases of tabbing:
- Generate letter headings with fixed layout
- Generate tables on invoices
- Can replace multi-columns (my personal use case)

Example 1:
#+ATTR_LATEX: :mode tabbing
| A | B |
|   | C |
is exported to 
\begin{tabbing}
\hspace{0.49\textwidth} \= \hspace{0.49\textwidth} \= \kill
A \> B\\
\> C\\
\end{tabbing}

Example 2:
#+ATTR_LATEX: :mode tabbing
| *Address* | Some street 100, box 101 |   | *GSM*   | 00 000 00 00 00  |
|         | Country                  |   | *Email* | mail@example.com |
the exported pdf is attached to this mail. 

Example 3:
#+ATTR_LATEX: :mode tabbing :align \hspace{2cm} \= \hspace{2cm} \= \kill
| name:    | A very long product name in this cell |   |
| options: | option 1                               | 1 |
|                | option 2                               | 1 |
|                | option 3                               | 0 |
the exported pdf is attached to this mail. 

Implementation details: 
- The table environment must be set to tabbing
- The cell separators must be set to \>
- The alignment string must be updated. 

Kind regards,
Bob Vergauwen
