When revise my manuscript, I found latexdiff can't label changes in tables. For example, there are two tex files before and after revision:

Before revision

\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}

After revision

\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}

The diff.tex is followed:

Actually, I have found the question lies on the \scalebox{}{}. If I don't use \scalebox, the diff.tex is enter image description here

This is what I want.

However, when use \scalebox, it would be

enter image description here

But in practice my table is very wide so I have to use \scalebox. My question is, is there any method to keep table fit to text width, meanwhile make latexdiff work?

  • do you really want to put a table in \scalebox ? It usually produces very poor result, it is usually far better to use \small or \tiny etc and use font size consistent with the rest of the document. Mar 7, 2019 at 7:53

\scalebox is treated as an un-safe command by default, hence being commented out by %DIFDELCMD. Appending \scalebox to the list of text command seems solve your problem. Check doc of latexdiff for more info.

latexdiff --append-textcmd="scalebox" old.tex new.tex > diff.tex

Selected lines of diff.tex

\begin{document}
      \begin{table}
          \centering
          \caption{\DIFaddbeginFL \DIFaddFL{New }\DIFaddendFL Example}
          \scalebox{0.8}{
          \begin{tabular}{lcc}
              \DIFdelbeginFL \DIFdelFL{A }\DIFdelendFL \DIFaddbeginFL \DIFaddFL{C }\DIFaddendFL & \DIFdelbeginFL \DIFdelFL{1 }\DIFdelendFL \DIFaddbeginFL \DIFaddFL{3 }\DIFaddendFL & \DIFdelbeginFL \DIFdelFL{1 }\DIFdelendFL \DIFaddbeginFL \DIFaddFL{3 }\DIFaddendFL \\
              \DIFdelbeginFL \DIFdelFL{B }\DIFdelendFL \DIFaddbeginFL \DIFaddFL{D }\DIFaddendFL & \DIFdelbeginFL \DIFdelFL{2 }\DIFdelendFL \DIFaddbeginFL \DIFaddFL{4 }\DIFaddendFL & \DIFdelbeginFL \DIFdelFL{2 }\DIFdelendFL \DIFaddbeginFL \DIFaddFL{4 }\DIFaddendFL \\
