如何在 \edef 宏中使用 \hline 生成表格

Question

有人知道如何添加\hline用于生成表的宏吗？

我的MWE

\documentclass{article}

\RequirePackage{tabularx}

\makeatletter
\newcounter{appdocs}
\setcounter{appdocs}{1}
\renewcommand{\theappdocs}{AD\arabic{appdocs}}
\newcommand{\appdocsCnt}[1]{%
  \theappdocs% Print counter
  \refstepcounter{appdocs}\label{#1}}% Mark with label

\newcommand{\applicabledocumententries}{}
\newcommand{\applicabledocument}[3]{%
\protected@xdef\applicabledocumententries{\applicabledocumententries \protect\appdocsCnt{#1} & #2 & #3 \protect\\}}

\newcommand{\applicabledocumentstable}{%
\begin{tabularx}{\textwidth}{p{2cm}|X|p{4cm}}%9.8
    \hline
    {\bfseries Ref.} & {\bfseries Title} & {\bfseries Reference and Issue} \\\hline
    \applicabledocumententries
    \hline
\end{tabularx}
}
\makeatother

\begin{document}

\applicabledocument{ad:1}{myTexta}{someDate}
\applicabledocument{ad:2}{myTextb}{anotherDate}
\applicabledocument{ad:3}{myTextc}{randomDate}
\applicabledocumentstable

\end{document}

产生

但我希望\hline在列表的每个条目之后都有。如何将 \hline 添加到宏扩展中？可能会朝着正确的方向发展，但我无法将其应用到我的例子。

Answer 1

您可以使用\DeclareRobustCommand来定义一个强大的\hline或（如示例中所示）以下列结尾的表格行\hline：

\documentclass{article}

\usepackage{tabularx}% Don't use \RequirePackage in document preamble after \documentclass

\makeatletter
\newcounter{appdocs}
\setcounter{appdocs}{1}
\renewcommand{\theappdocs}{AD\arabic{appdocs}}
\newcommand{\appdocsCnt}[1]{%
  \theappdocs% Print counter
  \refstepcounter{appdocs}\label{#1}}% Mark with label

\newcommand{\applicabledocumententries}{}
\DeclareRobustCommand*{\tabularnewlinewithhline}{\\\hline}
\newcommand{\applicabledocument}[3]{%
\protected@xdef\applicabledocumententries{\applicabledocumententries \protect\appdocsCnt{#1} & #2 & #3 \tabularnewlinewithhline}}

\newcommand{\applicabledocumentstable}{%
\begin{tabularx}{\textwidth}{p{2cm}|X|p{4cm}}%9.8
    \hline
    {\bfseries Ref.} & {\bfseries Title} & {\bfseries Reference and Issue} \\\hline
    \applicabledocumententries
\end{tabularx}
}
\makeatother

\begin{document}

\applicabledocument{ad:1}{myTexta}{someDate}
\applicabledocument{ad:2}{myTextb}{anotherDate}
\applicabledocument{ad:3}{myTextc}{randomDate}
\applicabledocumentstable

\end{document}

另外，您可以扩展并消除\protect之前的使用\applicabledocumententries：

\documentclass{article}

\usepackage{tabularx}
\makeatletter
\newcounter{appdocs}
\setcounter{appdocs}{1}
\renewcommand{\theappdocs}{AD\arabic{appdocs}}
\newcommand{\appdocsCnt}[1]{%
  \theappdocs% Print counter
  \refstepcounter{appdocs}\label{#1}}% Mark with label

\newcommand{\applicabledocumententries}{}
\DeclareRobustCommand*{\tabularnewlinewithhline}{\\\hline}
\newcommand{\applicabledocument}[3]{%
\protected@xdef\applicabledocumententries{\applicabledocumententries \protect\appdocsCnt{#1} & #2 & #3 \protect\\\protect\hline}}

\newcommand{\applicabledocumentstable}{%
\begin{tabularx}{\textwidth}{p{2cm}|X|p{4cm}}%9.8
    \hline
    {\bfseries Ref.} & {\bfseries Title} & {\bfseries Reference and Issue}
  \\\hline
    \let\protect\noexpand
    \edef\applicabledocumententries{\applicabledocumententries}%
    \applicabledocumententries
\end{tabularx}
}
\makeatother

\begin{document}

\applicabledocument{ad:1}{myTexta}{someDate}
\applicabledocument{ad:2}{myTextb}{anotherDate}
\applicabledocument{ad:3}{myTextc}{randomDate}
\applicabledocumentstable

\end{document}

Answer 2

下面我插入了一个宏\trules，它最初被设置为\relax（不可扩展）作为\applicabledocumententries构造的一部分，\trules然后被设置\hline为作为的一部分\applicabledocumentstable：

\documentclass{article}

\usepackage{tabularx}

\makeatletter
\newcounter{appdocs}
\renewcommand{\theappdocs}{AD\arabic{appdocs}}
\newcommand{\appdocsCnt}[1]{%
  \mbox{}\refstepcounter{appdocs}\label{#1}% Mark with label
  \theappdocs% Print counter
}

\newcommand{\applicabledocumententries}{}
\let\trules\relax
\newcommand{\applicabledocument}[3]{%
  \protected@xdef\applicabledocumententries{%
    \applicabledocumententries \protect\appdocsCnt{#1} & #2 & #3 \protect\\ \trules}}
\makeatother

\newcommand{\applicabledocumentstable}{%
  \let\trules\hline
  \begin{tabularx}{\textwidth}{ p{2cm} | X | p{4cm} }
    \hline
    {\bfseries Ref.} & {\bfseries Title} & {\bfseries Reference and Issue} \\
    \hline
    \applicabledocumententries
  \end{tabularx}
}
\makeatother

\begin{document}

\applicabledocument{ad:1}{myTexta}{someDate}
\applicabledocument{ad:2}{myTextb}{anotherDate}
\applicabledocument{ad:3}{myTextc}{randomDate}
\noindent
\applicabledocumentstable

\end{document}

不过，没有它，表格看起来会好得多。下面是使用booktabs：
