我正在尝试按照《美国政治科学评论》的风格编写一篇论文。以下是 cls 文件：

\section{Introduction}
\dropcap{This} is the introduction....
Then I want to introduct tab.1, which is stored in folder ``Table'' in my wd:
\input{Tables/t1}
\end{document}
表 t1 如下所示：
\begin{table}[hbt!]
\setlength{\tabcolsep}{10pt}
\caption{Summary statistics}
\label{tab:sumstat}
\centering
\begin{tabular}{|
S[table-format=3.3, table-align-text-post = false]
S[table-format=1.3, table-align-text-post = false]
S[table-format=1.3, table-align-text-post = false]
S[table-format=1.3, table-align-text-post = false]
S[table-format=1.3, table-align-text-post = false]}
Variables &\mc{Obs.} &\mc{Mean} &\mc{S.D.} &\mc{Min.} &\mc{Max.} \\ \midrule
HP &104,862 &0.848 &0.359 &\mc{0} &\mc{1} \\
CAF &104,862 &0.011 &2.148 &-7.427 &4.448 \\
GLOB &104,862 &0.199 &0.400 &\mc{0} &\mc{1}
\end{tabular}
\floatnote{Some notes}
\end{table}
当我尝试编译该文件时，收到以下错误消息：
! Missing \endcsname inserted.
<to be read again>
\__int_eval_end:
l.13 V
ariables &\mc{Obs.} &\mc{Mean} &\mc{S.D.} &\mc{Min.} &\mc{Max.} \\...
实际上，我以前能够编译该文件，但现在却不能。我尝试检查是否有任何 Unicode 字符，因为此错误可能由此引起，但似乎没有。
我删除了所有辅助文件，如 AUX 等。但它仍然不起作用。知道为什么会发生这种情况吗？
编辑
@UlrikeFischer。感谢回到 siunitx v2，让我能够编译该文件。我还在 t1 文件中添加了一个新行，即：
\begin{tabular}{|
S[table-format=3.3, table-align-text-post = false]
S[table-format=1.3, table-align-text-post = false]
S[table-format=1.3, table-align-text-post = false]
S[table-format=1.3, table-align-text-post = false]
S[table-format=1.3, table-align-text-post = false]
**S[table-format=1.3, table-align-text-post = false]**}
因为我意识到我有六列而不是五列。我只遇到了一个小问题。表 1 如下所示：
我不明白该如何修复它。为什么不显示“i”而是插入一个空格？
