When exporting to LaTeX, any footnotes inside a table are missing
the closing curly brace.
For example, a footnote such as:
| Field 1[fn:: A footnote.] | Field 2 |
is exported to LaTeX as:
\begin{center}
\begin{tabular}{l}
Field 1\footnote{A footnote. \\
\end{tabular}
\end{center}
Note that the closing curly brace is missing from the footnote.
The code for generating the LaTeX appears to be in org-latex.el at
line 2,463, and looks correct to me. Perhaps the closing brace is
removed later?
