我想将项目并排放置在两列布局中，中间留出一些空间（想象三列，中间一列是空的）。我想定义一个环境，为每个条目传递左列和右列的内容。到目前为止，我使用了并排的minipage（见下面的“版本 1”），它工作得很好，但不适用于较长的条目（见下文，当第二个条目移动到第 2 页时，第一页上剩下很多垂直空间）。然后我发现paracol。我再次定义了一个环境（见下面的“版本 2”），但正如您所见（在生成的 PDF 的第 3 页和第 4 页），引入了一些水平空间（为什么？）。左列中的条目不再完全右对齐，右列中的条目也不再完全左对齐。如何解决这个问题？
（如果有更好的解决方案（不使用 paracol），我也很想知道，因为即使paracol
使用包的功能，我也在使用脚注时遇到了问题。我需要的是列中的全部功能（因为我也在那里打印参考资料和其他东西）。此外，在我的例子中，列的宽度必然不同（我认为这排除了这种可能性multicol）并且可以扩展到页面）
\documentclass{scrartcl}
\usepackage{paracol}
\usepackage{calc}
\usepackage{titlesec}
\usepackage{blindtext}
\usepackage{tikz}
% Misc
\parindent0mm% to see better what's going on
\parskip1ex% define paragraph skip
% Define fractions of \textwidth for the columns (fractions are more suitable for \columnratio below)
\newcommand{\lcol}{0.24}% fraction of the left column
\newcommand{\mcol}{0.04}% horizontal space between the two columns
\newcommand{\rcol}{0.72}% fraction of the right column
% Bar for section headings (to see better what's going on)
\newcommand*{\sectionbar}{\raisebox{0.5ex}{\tikz\fill(0mm,0ex)rectangle+(\lcol\textwidth,0.5ex);}}
\titleformat{\section}{\Large\sffamily}{\sectionbar}{\mcol\textwidth}{}
\titlespacing{\section}{0mm}{1.4ex plus 1ex minus .2ex}{0ex plus .2ex}
% Version 1: minipage approach (works well but fails over pagebreaks)
\newcommand*{\entrymini}[2]{% arguments = (left entry, right entry)
\par
\begin{minipage}[t]{\lcol\textwidth}%
{\raggedleft #1\par}%
\end{minipage}%
\hfill%
\begin{minipage}[t]{\rcol\textwidth}%
#2%
\end{minipage}%
\par
}
% Version 2: paracol approach (introduces spurious space in the middle)
% Define an environment for switching to the 3-column layout
\newcommand*{\entrypara}[2]{% arguments = (left entry, right entry)
\columnratio{\lcol,\mcol,\rcol}
\begin{paracol}{3}
{\raggedleft #1\par}%
\switchcolumn%
\switchcolumn%
#2%
\end{paracol}
}
\begin{document}
This is the solution with minipages, which works for many entries except if there are page breaks:
\section{With minipages}
\entrymini{April 01, 2021}{\blindtext[1]}
\entrymini{April 29, 2021}{\blindtext[3]}
\clearpage\bigskip
This is the solution with paracol (which neither aligns the left column properly
on the right, nor aligns the right column properly on the left; where is the additional
horizontal space coming from?):
\section{With paracol}
\entrypara{April 01, 2021}{\blindtext[1]}
\entrypara{April 29, 2021}{\blindtext[3]}
\end{document}
更新（包含各种解决方案）
以下内容结合了paracolPieter 在本文评论中指出的解决方案。它还结合了 Pieter 和 Ulrike 指出的两种列表方法（但没有一种方法可以正确地为较长的项目换行）。
