在修改稿件时，我发现 latexdiff 无法以表格形式标注修改内容。例如，修改前后有两个 tex 文件：
改版前
\documentclass{article}
\usepackage{graphicx}
\begin{document}
\begin{table}
\centering
\caption{Example}
\scalebox{0.8}{\begin{tabular}{lcc}
A & 1 & 1 \\
B & 2 & 2 \\
\end{tabular}}
\end{table}
\end{document}
修改后
\documentclass{article}
\usepackage{graphicx}
\begin{document}
\begin{table}
\centering
\caption{New Example}
\scalebox{0.8}{
\begin{tabular}{lcc}
C & 3 & 3 \\
D & 4 & 4 \\
\end{tabular}}
\end{table}
\end{document}
diff.tex 如下：

其实，我发现问题出在\scalebox{}{}。如果我不使用 \scalebox，diff.tex 是
这就是我要的。
然而，当使用 \scalebox 时，它会
但实际上我的表格非常宽，所以我必须使用 \scalebox。我的问题是，是否有任何方法可以让表格适合文本宽度，同时使 latexdiff 正常工作？
答案1
\scalebox默认情况下被视为不安全命令，因此被注释掉%DIFDELCMD。附加\scalebox到文本命令列表似乎可以解决您的问题。查看文档latexdiff了解更多信息。
latexdiff --append-textcmd="scalebox" old.tex new.tex > diff.tex
精选的diff.tex
