我正在尝试使用以下代码为文档中的所有表格和图片生成书签。但是，使用此代码，表格 1 书签指向图 1，而图 2 书签指向表格 2，我无法找到图片和表格编号混淆的原因。
此外，使用此代码，整个标题都包含在书签中。我希望书签中只有简短的标题，但不知道该如何获取简短的标题。如能提供任何帮助，我将不胜感激。
谢谢！

书签应使用目标名称（由\captionmore 或 less 设置）。包hyperref用于\@currentHref存储当前目标名称。在您的情况下，您可以使用数字为图形和表格设置相同的目标名称，而无需进一步指定。还设置了一个新的锚点，而不是最佳位置，这里设置的\belowpdfbookmark锚点更好。\@currentHrefhyperref/caption
该包bookmark提供了更简单的界面来访问目的地：
\bookmark[
rellevel=1,
keeplevel,
dest=\@currentHref,
]{Table \thetable: #1}%
下一个问题：\caption它经常设置两次参数，因为它要检查字幕是否适合一行。可以使用 关闭此功能singlelinecheck=false。但这会影响单行字幕的格式。
\documentclass{article}
\usepackage{caption}
\usepackage{hyperref}
\usepackage{bookmark}
\captionsetup{singlelinecheck=off}
\makeatletter
\DeclareCaptionTextFormat{Tablebookmark}{%
\bookmark[
rellevel=1,
keeplevel,
dest=\@currentHref,
]{Table \thetable: #1}%
#1%
}
\captionsetup[table]{textformat=Tablebookmark}
\DeclareCaptionTextFormat{Figurebookmark}{%
\bookmark[
rellevel=1,
keeplevel,
dest=\@currentHref,
]{Figure \thefigure: #1}%
#1%
}
\captionsetup[figure]{textformat=Figurebookmark}
\makeatother
\begin{document}
\null\newpage
\begin{figure}[ht]
\centering
\rule{6cm}{3cm}
\caption{Figure caption text}
\end{figure}
\newpage
\begin{table}[ht]
\begin{tabular}{cc}

\end{tabular}
\caption[Table caption text]{This is a table with a very long caption text

\end{table}

\end{table}

\end{figure}如果这些浮动环境始终包含一个书签，则\end{table}可以将其用作设置书签的另一个位置\caption。由于包nameref将标题文本存储在宏中\@currentlabelname，因此可以在书签中使用它：
\documentclass{article}
\usepackage{caption}
\usepackage{hyperref}
\usepackage{bookmark}
\usepackage{etoolbox}
\makeatletter
\pretocmd\endtable{%
\bookmark[
rellevel=1,
keeplevel,
dest=\@currentHref,
]{Table \thetable: \@currentlabelname}%
}{}{\errmessage{Patching \noexpand\endtable failed}}
\pretocmd\endfigure{%
\bookmark[
rellevel=1,
keeplevel,
dest=\@currentHref,
]{Figure \thefigure: \@currentlabelname}%
}{}{\errmessage{Patching \noexpand\endfigure failed}}
\makeatother
\begin{document}
\null\newpage
\begin{figure}[ht]
\centering
\rule{6cm}{3cm}
\caption{Figure caption text}
\end{figure}
\newpage
\begin{table}[ht]
\begin{tabular}{cc}

\end{tabular}
\caption[Table caption text]{This is a table with a very long caption text

\end{table}
\newpage
