itemize 内部有 itemize，灰色标题部分周围的一些边框缺失

我对以下问题感兴趣我怎样才能绘制这个表 1？

我想知道如何在表格中的“itemize”中使用 itemize 我尝试了@Zarko 的代码，但没有成功，此外，我想知道为什么我无法获得灰色标题部分周围的所有 4 个边框

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[table]{xcolor}
\usepackage{tabularx}
\usepackage{enumitem}

\begin{document}
    \begin{center}
\setlist[itemize]{nosep,
                  topsep= 0pt,
                  partopsep=0pt,
                  leftmargin= *,
                  label=\textendash,
                  before=\vspace{-0.6\baselineskip},
                  after=\vspace{-\baselineskip}
                  }
\bfseries

根据我对这个问题的回答我怎样才能画出这张表 1：

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[table]{xcolor}
\usepackage{tabularx}
\usepackage{enumitem}
\usepackage{etoolbox}
\AtBeginEnvironment{center}{%
    \setlist[itemize,1]{nosep,
                        topsep     = 0pt,
                        partopsep  = 0pt,
                        leftmargin = *,
                        label      = \textendash,
                        before     = \vspace{-0.6\baselineskip},
                        after      = \vspace{-\baselineskip}
                        }
    \setlist[itemize]{  nosep,
                        leftmargin=*,

下面是带有嵌套 itemize 的代码，以及各种改进和简化：

    \documentclass{article}
    \usepackage[utf8]{inputenc}
    \usepackage[table, svgnames]{xcolor}
    \usepackage{tabularx, hhline}
    \usepackage{enumitem}
        \makeatletter
        \newcommand*{\compress}{\@minipagetrue}
        \makeatother
     \renewcommand{\tabularxcolumn}[1]{ >{\arraybackslash\compress}p{#1}}

    \begin{document}
        \begin{center}
    \setlist[itemize]{wide=0pt, nosep, leftmargin= * }
    \setlist[itemize, 1]{ label=\textendash, after=\vspace{-\baselineskip}}
    \setlist[itemize, 2]{ label=\textgreater}
    \setlength{\doublerulesep}{12pt}
    \setlength{\extrarowheight}{2pt}
    \bfseries
    \begin{tabularx}{\linewidth}{ | l | X | }
        \hhline{--}
    \rowcolor{WhiteSmoke!70!Lavender}\multicolumn{2}{|>{\centering\arraybackslash}p{\dimexpr\linewidth-2\tabcolsep}|}{%
        Very long text here and centered
        Very long text here and centered
        Very long text here and centered} \\
     % \hline \noalign{\vspace*{12pt}}
    %\multicolumn{2}{c}{} \\
        \hhline{==}
    Description & \begin{itemize}
                    \item long text bla bla bla bla
                    \item long text bla bla bla bla
                    \begin{itemize}[]
                    \item long text bla bla bla bla
                    \item long text bla bla bla bla
                    \item long text bla bla bla bla
                    \item long text bla bla bla bla
                    \end{itemize}
                    \item long text bla bla bla bla
                    \item long text bla bla bla bla

        \hhline{--}
    Addition & long text bla bla bla bla long text bla bla bla bla\\
        \hhline{--}
    \end{tabularx}
        \end{center}

    \end{document}

  • 第一个表不包括before和after选项，以便纠正itemize环境上方和下方的间距。

  • 第二个表格包括这些选项。正如我们所见，负数vspaces 会干扰嵌套itemize环境，因为它们会累加。

  • 第三个表格再次不包含before和after选项，但包括一些手动调整，以摆脱第一级itemize环境上方和下方不必要的空白。

最后一个表格也可以用以下 MWE 来生成，它使用两个不同的、新定义的环境来表示表格单元格内的itemize第一级和后续级环境：itemize

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{tabularx}
\usepackage{enumitem}

\newlist{tabitemizefirst}{itemize}{1}
\newlist{tabitemizesecond}{itemize}{1}

\setlist[tabitemizefirst]{nosep,
                  topsep= 0pt,
                  partopsep=0pt,
                  leftmargin= *,
                  label=\textendash,
                  before=\vspace{-0.6\baselineskip},
                  after=\vspace{-\baselineskip}
                  }

\setlist[tabitemizesecond]{nosep,
                  topsep= 0pt,
                  partopsep=0pt,
                  leftmargin= *,
                  label=\textendash,
                  }

\begin{document}
\begin{tabularx}{\linewidth}{ | l | X | }
    \hline

                \item   long text bla bla bla bla
