[O] [PATCH] org-e-latex: Tables get correct amount of vertical space

[Myles English]

Hi,

This patch replaces every occurence of the \begin{center} environment
with \centering in the file contrib/lisp/org-e-latex.el.  I have tested
the export of a basic table and it works but not sure if all the
replacements are correct.

( BTW, this issue came to light using the nag package like this:
\RequirePackage[l2tabu, orthodox]{nag} )

Myles

Subject: [PATCH] org-e-latex:  Tables get correct amount of vertical space

* contrib/lisp/org-e-latex.el: Replaced \begin{center} ..\end{center}
  environments with \centering declarations.

Using both \begin{table} and \being{center} environments leads to double
the vertical space around the float, whereas \centering adds none.
