LaTeX 中的引用表格行

Question 1

这是一个使用新列类型的方法N，它会自动增加rowcntr，因为\label应该在后台使用计数器（尽管\@currentlabel也可以进行写入操作，请参阅 gernot 的回答）。

使用rowcntr每个新命令或使用tabular新表时会重置（即计数器已增加）\captiontable

在我看来，行号应该以表号作为前缀，以便在出现多个表问题时避免混淆所指的问题。

超链接确实有效！

我还将错误放置的表格标签移到了它所属的位置，即后使用\caption！

Question 2

根据定义

\makeatletter
\newcommand\newtag[2]{#1\def\@currentlabel{#1}\label{#2}}
\makeatother

在序言中你可以使用命令

\newtag{word}{label name}

在此点插入并使用或word在此处之前或之后引用它。\ref{label name}\pageref{label name}

\documentclass{article}
\usepackage[utf8]{inputenc}

\begin{table}[H]
\centering
\label{tab:Q1}
\begin{tabular}{|c|c|l|l|}
\hline
Number & Theory & Question & Explanation  \\ \hline
\newtag{1}{que:whyisit} & B & Why is it you think ... & This is a good question\\
\newtag{2}{que:doyouthink} & A & Do you think  ... & This Is also a good question\\
\newtag{3}{que:isitcorrect} & B & is it correct that you think ... & This is question \\ \hline
\end{tabular}

\end{table}
Question \ref{que:whyisit} is about ... \\
Question \ref{que:doyouthink} is about ... \\
Question \ref{que:isitcorrect} is about ... 

\end{document}

如果你愿意，你可以删除\label- 功能\newtag并只定义

\makeatletter
\newcommand\newref[1]{#1\def\@currentlabel{#1}}
\makeatother

并将其用作

\newref{1}\label{que:whyisit} & ...
\newref{2}\label{que:doyouthink} & ...

Question 3

做出反驳也是我会做的，但是围绕这个解决方案有 2 个答案（均为 +1），似乎足够了。

作为概念证明，如果计数器不是解决方案，则答案会有所不同，因为“数字”无法自动计算和排版，甚至不是数字。想想一些分数、识别号（不一定是有序和连续的）、考试中问题的值等，或者一些十六进制代码等。

由于您使用的是hyperref，因此您可以在此处使用\hypertarget和\hyperlink。缺点是交叉引用的文本不是自动的，但仍是活动链接，优点是单元格内容和引用文本都是免费的，因此您可以使用标识键作为 F24E，引用拼写出的数字（“nine”而不是“9”）等。示例：

\documentclass{article}
\usepackage{booktabs}
\usepackage[colorlinks]{hyperref}
\parskip2em\parindent0pt
\begin{document}

\begin{tabular}{ccll}\toprule
Number                        & Theory & Question                & Explanation  \\\midrule
\hypertarget{whyisit}{43}     & B      & Why is it you think ... & This is a good question\\
\hypertarget{doyouthink}{36}  & A      & Do you think  ...       & This is also a good question\\
\hypertarget{isitcorrect}{13} & B      & is it correct that  ... & This is question \\\bottomrule
\end{tabular}

Question \hyperlink{whyisit}{43} is about ... \\
Question  \hyperlink{doyouthink}{here (36)} is about ... \\
Question \hyperlink{isitcorrect}{13} is about ... 

\end{document}

对于任意数字（但仅限数字），一个更奢侈的替代方案可能是spreadtab包。交叉引用的编号是自动的，但不是活动链接。但是，如果您需要对这些数字进行一些数学运算（总分之和等），它可能很有用。该示例显示了表格内部和外部的交叉引用。下面的示例显示可以通过表格内的单元格位置调用值，或者使用正文中的标签进行交叉引用：

\documentclass{article}
\usepackage{spreadtab,booktabs}
\begin{document}

\begin{spreadtab}{{tabular}{ccll}}
@Number        & @Theory & @Question                & @Explanation\\\midrule
43tag(whyisit) & @B      & @Why is it you think ... & @This is a good question\\
36             & @A      & @Do you think ...        & @This is also a good question\\
13             & @B      & @is it correct that ...  & @This is question \\\bottomrule
\addlinespace[.5ex]
\multicolumn{4}{l}{Question :={a4} in this table is about ... }\\
\end{spreadtab}

\bigskip\bigskip\bigskip

Question \STtag{whyisit} in that table is about ... 

\end{document}
