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

- Can span multiple pages (also possible with long tables).

- Cell width is fixed and does not depend on the content.

- Cells can overflow.

You do not need an extra progn inside let.
