我用threeparttable它来格式化我的表格。我还使用括号来引用脚注。如下图所示，脚注的第二行[a]没有对齐。以 开头的行0.0从最左边开始。
我该如何纠正这个问题？
谨致问候，wewa00
PS：这是重现此问题的示例 LaTeX 代码。

以下解决方案可实现您的格式化目标。请注意，执行 不是一个好主意\def\TPTnoteSettings{\setlength\labelwidth{1em}}，因为这样做会破坏宏的默认设置。这就是为什么下面的代码包含指令
\apptocmd{\TPTnoteSettings}{\setlength\labelwidth{1em}}{}{}
在下面的代码中，我还清理并简化了您的前言代码。顺便说一句，该booktabs包与“支持表格居中”完全无关。相反，它提供了宏（例如\toprule和\bottomrule）来绘制间距合适的水平线。还请注意，\begin{threeparttable}指令应该位于\caption语句之前，而不是之后。
