我已经尝试了好几个小时来寻找一个令人满意的表格脚注问题解决方案。我遇到的所有方法似乎都无法正常工作。不过，tabularx软件包文档中说明tabularx支持\footnote。
我尝试过使用
\footnote{footnote text}
命令tabularx，它肯定会显示表格中的脚注（哈利路亚！），但不显示脚注文本（哈利路亚不是那么多）。
我也尝试过
\footnotemark[footnote#]
和
\footnotetext[footnote#]{footnote text}
表格下面的某个地方，它工作得很好，只是你必须自己跟踪计数器，当你\footnote在页面的文本的其他位置插入正常时会导致悲剧。
最好的解决方案是，如果可以在表格中添加字母脚注并为文本编号，但\footnotemark不支持使用字母作为数字。
那么...有人了解tabularx脚注是如何工作的吗？
一位 MWE 表示：
\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}}
编辑：David Carisle 提供的解决方案在一天左右的时间内运行良好。我不知道它为什么停止工作，但脚注文本和参考资料在 minipage-tabularx 环境中都停止工作了。MWE：

答案2
大概某人明白tabularx:-)
中的脚注tabularx旨在使页脚注与文本一起放在页面末尾。如果您没有看到文本，则很可能是您将表格放在了其他框中（例如浮动框），无论脚注是否在表格中，都会阻止脚注。
如果您想要表格注释，标准的乳胶方式是将其放入tabular，minipage然后脚注出现在小页面的末尾。
或者你可能更喜欢这个答案中的代码
\footnotetext 为许多 \footnotemark 编号 - 自动解决方案
您编辑的 MWE 作品为我提供了脚注：
文件列表显示你的 MWE 加载了 166 个文件，其中大约所有文件都是不是这个例子需要它，所以要求任何人调试都太过分了。我在下面附上了我的清单。我会先删除你不使用的所有内容在这个例子中从其他答案 siunits 中推送/弹出脚注（以及所有 l3exp 代码），事实上据我所知，您的 MWE仅有的使用tabularx后，您很可能会得到脚注，然后只需放回您认为需要的软件包即可。如果脚注消失，则说明该软件包存在问题。
