这里是我的文档的一个片段。
\section{Events}
\begin{multicols}{2}
\subsection{Monday}
\textit{10:15am–11:15am}\dotfill\ Panel 2\smallskip\\
{Text here,\\
text there}
\vfill\columnbreak
\subsection{Wednesday}
\textit{9:00am–10:00am}\dotfill\ Panel 1\smallskip\\
{Text over there}
\newline % 3rd-line padding
\end{multicols}
\begin{multicols}{2}
\noindent\textit{12:45pm–1:45pm}\dotfill\ Panel 1\smallskip\\
{Text down here}
\vfill\columnbreak
\noindent\textit{11:30am–12:30pm}\dotfill\ Panel 2\smallskip\\
{Text everywhere}
\end{multicols}
它看起来是这样的。它或多或少就是我想要的样子。
问题是这些列会无限期地延续，并且可能会移动和替换条目。显然，按照我上面构建的方式，任何这样的小调整都是不切实际的。还有一个额外的不便之处是，当一对条目的长度不同时，我必须填充较短的条目，否则就会出现这样的混乱。
我的问题是：我怎样才能做得更好？
答案1
这只是初步解决方案——但我不建议使用 8 个参数。稍后我将尝试使用键值语法进行更新。
\documentclass{article}
\usepackage{etoolbox}
\usepackage{longtable}
\DeclareRobustCommand{\timedisplayline}[2]{%
\textit{#1} \dotfill\ #2
}
\DeclareRobustCommand{\tableline}[8]{%
\protect\subsection{#1} & \protect\subsection{#4} \tabularnewline
\timedisplayline{#2}{#3} & \timedisplayline{#5}{#6} \tabularnewline
\ifblank{#7}{}{#7} & \ifblank{#8}{}{#8} \tabularnewline
}
\begin{document}
\section{Events}
\begin{longtable}{*{2}{p{0.4\textwidth}}}
\tableline{Monday}{10:15am-11:15am}{Panel 2}{Wednesday}{9:00am-10:00am}{Panel 1}{Some text}{Other text}
\tableline{Monday}{10:15am-11:15am}{Panel 2}{Wednesday}{9:00am-10:00am}{Panel 1}{}{}
\tableline{Monday}{10:15am-11:15am}{Panel 2}{Wednesday}{}{Panel 4}{}{}
\end{longtable}
\end{document}
更新更好的解决方案
\lefttitle我添加了名为、lefttime和的键值leftpanel及其等价物。它们仅在不为空时才显示。单元格的分组避免了明确清除它们的需要，但它们最初都是空的。leftdescription\right...
这样，就不需要记住哪个参数对应哪个条目。
最好的办法是对左表和右表使用两个单独的命令。
