自动调整 paracol（或 minipage、tabularx 等）中的左列宽度以适合未换行的文本

Question

我对 LaTeX 还很陌生。在 MWE 中，我需要标题和额外信息文本永不换行。我需要根据需要换行小细节，同时充分利用空间。我认为如果左列宽度自动设置为未换行的文本内容宽度，那么一切都应该按预期工作。

实际文本将由 Python 脚本定期生成，因此，如果可能的话，我需要它在没有人工干预的情况下工作。并且还可以与目录中的正常分段等配合使用。

我并没有完全依赖 paracol，但与我尝试过的其他解决方案（例如 tabularx 等）相比，我更接近所需的结果。我在网上找到的一些解决方案似乎有效直到我包含了 \section 然后中断。

我觉得这应该比我做的要容易？

\documentclass[12pt,letterpaper]{scrartcl}
\usepackage[english]{babel}

\usepackage{paracol}

\begin{document}

    \setlength{\columnseprule}{0.4pt}
    % set 3.9in automatically, rather than manually
    \setcolumnwidth{3.9in, \fill}
    \begin{paracol}{2}
        \section{Header That Goes Here (Longer)}
    
        {\bfseries\large Extra info Goes Here}
        \switchcolumn
        \raggedleft
        {\footnotesize Small details go here}
    \end{paracol}
    
    \clearpage
    
    \setlength{\columnseprule}{0.4pt}
    % set 4.6in automatically, rather than manually
    \setcolumnwidth{4.6in, \fill}
    \begin{paracol}{2}
        \section{Header That Goes Here}
        
        {\bfseries\large Extra info Goes Here (Sometimes is a bit longer)}
        \switchcolumn
        \raggedleft
        {\footnotesize Small details go here}
    \end{paracol}
    
    \clearpage
    
    \setlength{\columnseprule}{0.4pt}
    % set 3.9in automatically, rather than manually
    \setcolumnwidth{3.9in, \fill}
    \begin{paracol}{2}
        \section{Header That Goes Here (Longer)}
        
        {\bfseries\large Extra info Goes Here}
        \switchcolumn
        \raggedleft
        {\footnotesize Small details go here, and these are sometimes longer}
    \end{paracol}

\end{document}

Answer 1

您可以使用 tabularx，但左侧文本太长，无法换行......

\documentclass[12pt,letterpaper]{scrartcl}
\usepackage[english]{babel}
\usepackage{tabularx}
\newcommand\zsec[3]{%
\par
\bigskip
\noindent
\begin{tabularx}{\linewidth}{@{}l|>{\raggedleft\arraybackslash}X@{}}%
\large\sffamily\bfseries\refstepcounter{section}\thesection. #1&\\[5pt]
\mbox{\bfseries\large#2}&\footnotesize \vspace*{-30pt} #3\end{tabularx}\par}


\begin{document}


\zsec
{Header That Goes Here (Longer)}
{Extra info Goes Here}
{Small details go here}

\zsec
{Header That Goes Here}
{Extra info Goes Here (Sometimes is a bit longer)}
{Small details go here}
    
\zsec
{Header That Goes Here (Longer)}
{Extra info Goes Here}
{Small details go here, and these are sometimes longer}

\end{document}
