我的主要文本使用 1.5 倍行距，现在表格下方的注释也是 1.5 倍行距。我希望它们采用单倍行距（我的其他所有表格都没有这个问题）。如果我只是在 threeparttable 中使用 tabular 环境，我就会得到我想要的脚注外观，但我似乎无法为这个表格重现单倍行距。我该如何修复这个表格的代码，以便我可以将表格拉伸到页面文本的宽度，但我的脚注以单倍行距显示在表格下方？任何帮助都将不胜感激。

答案1
(旁白：在 OP 指出他/她用来更改文档默认行距的方法以及使代码可编译所需的包后，我进行了大量更新/简化。)
我有几点建议：
由于您正在使用
setspace包和指令\onehalfspacing来更改整个文档的默认行距，因此您可以\singlespacing在环境启动后插入指令ThreePartTable以在本地切换到单倍行距。longtable由于所有这些\multicolumn{1}{l}{...}和包装器，环境的内容变得不必要地复杂\multicolumn{1}{c}{...}。据我所知，这些包装器是不必要的。（它们只会造成代码混乱。）由于您正在使用该
threeparttablex包，因此您可以编写\tnote{a}和，\item[a]而不是更费力的\textsuperscript{a}和\item \textsuperscript{a}等。
这是您提供的示例代码的简化版本。我注释掉了加载 MWE 中实际未使用的包的指令。顺便说一句，由于包会加载，因此单独加载graphics和是没有意义的。同样，如果您还要加载，请不要加载。graphicxrotatinggraphicxcolorxcolor
