\章节标题样式

Question

昨天，我看到了一篇关于我喜欢的章节标题样式的帖子。我想知道您是否可以帮助我实现相同的模型（尽管与我想要的模型存在某些差异）。提前谢谢您。

 \documentclass[a4paper]{book}
 \usepackage[T1]{fontenc}
 \usepackage{libertine}
 \usepackage[table]{xcolor}
 \makeatletter
 \def\@part[#1]#2{%
  \ifnum \c@secnumdepth >-2\relax
  \addcontentsline{toc}{chapter}{\thechapter\hspace{1em}#1}%
 \else
  \addcontentsline{toc}{chapter}{#1}%
 \fi
\markboth{}{}%
\reset@font
\parindent \z@ 
\vspace*{10\p@}%
\hbox{%
 \vbox{%
  \hsize=7mm%
  \begin{tabular}{@{}p{7mm}@{}}
    \makebox[7mm]{\scshape\strut\small\chaptername}\\
    \makebox[7mm]{\cellcolor{black}\Huge\color{white}\bfseries\strut\thechapter\rule[-4cm]{0pt}{4cm}}%
  \end{tabular}%
  \makebox(0,0){\put(-10,-100){\fbox{\phantom{\rule[-4cm]{7mm}{4cm}}}}}
  }%
\kern-2pt
\vbox to 0pt{%
   \tabular[t]{@{}p{1cm}p{\dimexpr\hsize-2.1cm}@{}}\hline
      & \Huge\itshape\rule{0pt}{1.5\ht\strutbox}#1\endtabular}%
   }%
  \cleardoublepage
%  \vskip 100\p@
}
       \makeatother

   \begin{document}
   \chapter{Books in \LaTeX}
