Footnotes in tables are deferred. Each `\pandocfootnotetext` must
be matched to its `\pandocfootnotemark`, and the text of a nested
note must come after the text containing its mark.

The LaTeX reader handles this output, ignoring the definitions of
the macros from the template:

```
% pandoc -f latex -t markdown
\makeatletter
\protected\def\pandocfootnotemark#1{\footnotemark{}%
  \expandafter\xdef\csname pandoc@fn@#1\endcsname{%
    \noexpand\pandoc@fnrestore
    {\unexpanded\expandafter{\@thefnmark}}%
    {\ifdefined\Hy@footnote@currentHref
       \unexpanded\expandafter{\Hy@footnote@currentHref}\fi}}}
\def\pandoc@fnrestore#1#2{%
  \gdef\@thefnmark{#1}%
  \ifdefined\Hy@footnote@currentHref\gdef\Hy@footnote@currentHref{#2}\fi}
\newcommand\pandocfootnotetext[1]{%
  \csname pandoc@fn@#1\endcsname\@footnotetext}
\makeatother

\begin{tabular}{ll}
x\pandocfootnotemark{2} & y\pandocfootnotemark{3} \\
\end{tabular}
\pandocfootnotetext{2}{outer \pandocfootnotemark{1}}
\pandocfootnotetext{1}{inner note}
\pandocfootnotetext{3}{second}
^D
  ------- -------
  x[^1]   y[^2]
  ------- -------

[^1]: outer [^3]

[^2]: second

[^3]: inner note
```

It also handles adjustments to the footnote counter with
`\footnotemark` and `\footnotetext`, as in output from
earlier versions of pandoc:

```
% pandoc -f latex -t markdown
\begin{tabular}{ll}
x\footnotemark{} & y\footnotemark{} \\
\end{tabular}
\addtocounter{footnote}{-1}
\footnotetext{first}
\addtocounter{footnote}{1}
\footnotetext{second}
^D
  ------- -------
  x[^1]   y[^2]
  ------- -------

[^1]: first

[^2]: second
```
