我正在通过外部脚本向 LaTeX 模板提供内容，而阻碍我的最后一个格式化步骤是：\equispace[6]{a,b,c}{d,e,f}{g,h}{i,j,k,l}{m,n,o}{p,q,r,s,t}将参数转换为这种数组的宏，
当数组延伸到整个线宽时，项目组间距相等，并围绕其自己的组居中。我尝试使用 tabularx 和 minipage，但这比我有限的 TeX 技能允许的要棘手。请注意，我事先知道每个组中有多少个项目，因此如果有很好的方法来解析内容，我可以使用硬编码模板。
答案1
忽略[6]论点（参见问题下的评论）然后
\documentclass{article}
\newcommand\equispace[6]{%
\begin{center}%
\begin{tabular}{@{}c@{}}\zz{#1}\\\zz{#4}\end{tabular}\hfill
\begin{tabular}{@{}c@{}}\zz{#2}\\\zz{#5}\end{tabular}\hfill
\begin{tabular}{@{}c@{}}\zz{#3}\\\zz{#6}\end{tabular}%
\end{center}%
}
\makeatletter
\def\zz#1{\@for\z:=#1\do{\z\,}}
\makeatother
\begin{document}
\equispace{a,b,c}{d,e,f}{g,h}{i,j,k,l}{m,n,o}{p,q,r,s,t}
\end{document}
答案2
如果你运行外部脚本，它可能会输出如下内容：
\begin{tabular*}{\textwidth}{@{}c@{\extracolsep{\fill}}c@{\extracolsep{\fill}}c@{}}
a b c & g h & m n o\\
d e f & i j k l & p q r s t
\end{tabular*}
输出：
带有线条：
\begin{tabular*}{\textwidth}{|@{}c@{\extracolsep{\fill}}c@{\extracolsep{\fill}}c@{}|}
\hline
a b c & g h & m n o\\
\hline
d e f & i j k l & p q r s t\\
\hline
\end{tabular*}
编辑：
下面的代码应该能够解析任意数量的参数（并像您的示例中那样对其进行排序）。代码可能并不完美，也许可以改进，但它确实可以处理迄今为止我遇到的所有问题。

该命令\equispace接受两个可选参数，第一个参数<>是列数，默认为 3，第二个参数[]是参数数，默认为 6。
输出 5 列和 96 个参数：
答案3
listofitems来救援！
使用语法：\equispace{a,b,c/d,e,f/g,h/i,j,k,l/m,n,o/p,q,r,s,t}
\documentclass{article}
\usepackage{listofitems,stackengine,pgffor}

\newcommand\equispace[1]{%
\setsepchar[;]{/;,}%
\readlist*\mylist{#1}%
\noindent\leavevmode\rlap{\stackunder[-\fboxrule]{\mybox}{\mybox}}%
~\foreach\x in{1,3,...,\listlen\mylist[]}{%

\def\stacktype{L}%
\stackunder{\foreachitem\y\in\mylist[\x]{\ifnum\ycnt=1\else\ \fi\y}}%
