如果需要，如何让描述列表中的标签文本在标签区域中换行多行？

Question

我使用该enumitem包来定制描述列表。下面是 MWE 打印的一些虚构的个人信息：

\documentclass{article} 
\usepackage{enumitem}
\setlist[description]{leftmargin=5em, labelindent=0em, labelwidth=4.5em,
                      align=right}

\begin{document} 
\begin{description}
\item[Address]
3 Whole St, Wondertown WXY 2722
\item[Email]
[email protected]
\item[Phone]
123 55 66 78
\item[Secondary Phone]
123 78 66 55
\item[Nationality]
Wonderland, Republic of Home and Mother Country
\item[Security Clearance]
National Clearance 13.2 with a very, very, very,
very, very, very, very, very, very, very, very,
very, very, very, very long explanation
\end{description}

\end{document}

输出基本上是这样的：

    Address   3 Whole St, Wondertown WXY 2722
      Email   [email protected]
      Phone   [phone]
Secondary Phone [phone]
Nationality   Wonderland, Republic of Home and Mother Country
Security Clearance National Clearance 13.2 with a very, very, very,
              very, very, very, very, very, very, very, very, very,
              very, very, very long explanation

有些标签不适合 - 当然\setlist[description]我可以增加必要的尺寸，但我宁愿不移动标签/文本分隔的位置。相反，我希望标签能够换行在标签区域像这样的多行：

    Address   3 Whole St, Wondertown WXY 2722
      Email   [email protected]
      Phone   [phone]
  Secondary   123 78 66 55
      Phone
Nationality   Wonderland, Republic of Home and Mother Country
   Security   National Clearance 13.2 with a very, very, very,
  Clearance   very, very, very, very, very, very, very, very, very,
              very, very, very long explanation

理想情况下，标签中的换行符会自动出现在空格处。有没有办法用enumitem或其他方式实现这一点？

注 1：我看到了 stackexchange 上的问题“强制项目内的长文本换行”，但我无法让它适用于我的情况。

笔记2：我不想改变我使用的环境。tabular类似的环境当然可以很好地适应，但是整个输入文本已经在描述列表中设置了，所以我想保持这种方式。

Answer 1

您可以定义一种类似于多线的新样式，但是

• 你必须设置更好的标签宽度和

• \\~如果描述文本太短，则必须插入空行。

  \documentclass{article}
  \usepackage{enumitem,calc}
  
  \makeatletter 
  \def\enit@align@parright{%
    \def\enit@align##1{%
      \nobreak
      \strut\smash{\parbox[t]\labelwidth{\raggedleft##1}}}}
  
  \def\enit@style@multilineright{%
    \enit@align@parright
    \enit@calcset\labelindent\z@{0pt}%
    \enit@calcset\leftmargin\thr@@!}
  \makeatother    
  
  \setlist[description]{labelwidth=\widthof{\bfseries Nationality},
                        style=multilineright}
  
  \begin{document}
