这是\g@addto@macro 附加位置特定引用。在这种情况下，我使用 来应用自动表格填充\immediate\write\@auxout。原因是我想将整个表格定位在文档的开头。但正如您所见，引用一直在更新，而我不知道如何使用\expand或\noexpand控制这种行为。下面的最小示例是不言自明的，也展示了我想要实现的目标。表格外的引用表现如预期。但是，表格内的引用却没有（我认为问题出在命令 上\addtotable）。我的问题是，如何更改定义的命令，以便表格也能正确更新？

答案1
您\immediate\write\@auxout{\unavoided{...}}将停止所有扩展，但您需要扩展一些命令。相反，您可以使用\protected@write\@auxout{}{...}通过 LaTeX 机制控制扩展\protect。
此外，还\refthis必须进行更改以允许扩展，您大多必须在此处添加括号：
\newcommand{\refthis}{%
\protect\hyperlink{\@currentHref}{\@currentlabel}
}
修复起来比较困难\refthistype。如果不更改大量 hyperref 内部结构，当前版本就无法实现扩展，但你可以通过一些小技巧来避免这种情况：
\DeclareRobustCommand\@currentlink[1]{\hyperlink\@currentHref{\csname the#1\endcsname}}
\newcommand\refthistype[1]{%
\begingroup
\protect\Hy@localanchornametrue
\protect\@nameuse{c@#1}=\the\value{#1}
\protect\hyper@makecurrent{#1}%
\@currentlink{#1}%
\endgroup
}
结合起来，给出了一个有效的例子：

\usepackage{hyperref}
\newcommand\foorows{}
\newcommand\foo{%
\begin{table}[htp]

\hline
\end{tabular}
\end{table}}
\makeatletter
\DeclareRobustCommand\realaddtotable[1]{\g@addto@macro\foorows{#1 \\}}
\newcommand\addtotable[1]{%
\protected@write\@auxout{}{\realaddtotable{#1}}%

\newcommand\refthistype[1]{%
\begingroup
