自定义描述列表

Question

好的伙计们，我有一个稍微奇怪的设置，我希望有人可以帮助我。

我有一个自动生成的.tex 文件（由 pandoc 从 markdown 制作），其中有一个描述列表，如下所示：

\begin{description}
\item[Item One]
This is the text that goes with item one
\item[Item Two]
This one is much nicer
\item[Item Three]
The third item is by far my favourite though.
\end{description}

该块是自动生成的，所以我无法编辑它。

我试图让输出在视觉上匹配不同的文件格式，如下所示：

通过使用这个enumitem包，我已经非常接近了。我可以编辑序言，到目前为止我有以下内容：

\usepackage{enumitem}
\setlist[description]{style=multiline,leftmargin=5.5cm, itemsep=0cm}
\renewcommand{\descriptionlabel}[1]{
    \hspace{\labelsep}
    \colorbox{lightgrey}{
        \parbox{4.8cm}{
            \textbf{#1}
        }\par
    }
}

这给了我如下的输出：

我对 LaTeX 还不太熟悉，我只能做到这些。有人知道我是否可以在项目描述周围添加边框吗？此外，我是否可以连接项目标题并增加文本周围的填充。

谢谢！

让我重新定义我的问题以使其更清楚。如何让描述项（而不是标签）有边框？基于这个最小的例子：

\documentclass[12pt]{article}

\usepackage{enumitem}
\setlist[description]{style=multiline, leftmargin=5.5cm, itemsep=0cm}

\begin{document}

%% Start of auto-generated code: can't edit this
\begin{description}
\itemsep1pt\parskip0pt\parsep0pt
\item[Item One]
This is the text that goes with item one
\item[Item Two]
This one is much nicer
\item[Item Three]
The third item is by far my favourite though.
\end{description}
%% end of auto-generated code

\end{document}

这是一个使用tikzmarkTikZ 的库和etoolbox自动添加description标签的彩色区域和描述的框架；代码需要运行三次才能稳定：

代码：

\documentclass[12pt]{article}
\usepackage{enumitem}
\usepackage{etoolbox}
\usepackage{tikzpagenodes}
\usetikzlibrary{tikzmark,calc}

\newcounter{colordesc}
\newlength\longestlabel
\setlength\longestlabel{5.5cm}

\setlist[description]{style=multiline, leftmargin=\longestlabel, itemsep=0cm}

\AtBeginEnvironment{description}{%
  \stepcounter{colordesc}%
  \begin{tikzpicture}[overlay,remember picture]
  \fill[gray!60] 
    ( $ (pic cs:start-\thecolordesc) + (-25pt,-1.2\topsep) $ ) 
      rectangle 
    ( $ ({pic cs:start-\thecolordesc}|-{pic cs:end-\thecolordesc}) + (\longestlabel-25pt,-.5\topsep) $ );
  \draw[gray!60] 
    ( $ (current page text area.east|-{pic cs:start-\thecolordesc}) + (0,-1.2\topsep) $ )
      -- 
    ( $ (current page text area.east|-{pic cs:end-\thecolordesc})  + (0,-0.45\topsep) $ );
  \end{tikzpicture}%
  \tikzmark{start-\thecolordesc}%
}
\AtEndEnvironment{description}{%
  \tikzmark{end-\thecolordesc}%
}
\AtEndEnvironment{description}{%
  \tikz[overlay,remember picture]\draw[gray!60]
    ( $ (current page text area.west|-{pic cs:end-\thecolordesc}) + (0,-.45\topsep) $ ) 
    -- ++(\textwidth,0);%
}

\renewcommand*\descriptionlabel[1]{%
  \tikz\draw[overlay,gray!60]
    (0,.8\baselineskip) -- 
    (\textwidth,.8\baselineskip);%
    \hspace\labelsep\normalfont\bfseries #1%
}

就目前的形式而言，此解决方案不能处理分页符；允许分页符所需的修改并不特别困难，只要我有时间（也许这个周末之后），我就会提供它。
