I've been trying to find a satisfying solution to the footnotes-in-tables-problem for hours now. Nothing I come across seems to work the way it should. Still, in the tabularx package documentation it is stated that tabularx supports \footnote.
I've tried using the
\footnote{footnote text}
command in the tabularx environment, and it for sure shows the footnote in the table (hallelujah!), but not the footnote text (not so much hallelujah).
I've also tried
\footnotemark[footnote#]
with
\footnotetext[footnote#]{footnote text}
somewhere underneath the table, which works perfectly fine, except that you have to keep track of the counters yourself, which results in tragedy when you insert a normal \footnote elsewhere in the text on the page.
The best solution would be if one could have lettered footnotes in the table and numbered for the text, but \footnotemark does not support using letters as numbers.
So… does anyone understand how tabularx works with footnotes?
A MWE:
\begin{table}[!h]
\centering
\caption{Characteristics of the most common reactor types}
\label{tab:reactor-properties}
\begin{tabularx}{0.8\textwidth}{*{4}{L}}
\toprule
Type & Fuel \footnotemark[1] & Moderator & Coolant \\
\midrule
LGR \footnotemark[2] & \ce{UO2}, enr. & Graphite, \ce{H2O} & \ce{H2O}(\emph{l}) \\
\bottomrule
\end{tabularx}
\end{table}
\footnotetext[1]{enr. = enriched in \ce{^{235}U}, nat. = natural}
\footnotetext[2]{There were four such reactors at the Chernobyl plant at the time of the accident \cite{nuclear-energy}}
EDIT: The solution offered by David Carisle worked perfectly for a day or so. I have no idea why it stopped working, but both the footnote-text and references have stopped working in a minipage-tabularx-environment. A MWE:
