我想重新创建这本书的标题：
https://books.google.de/books?id=ybEmCgAAQBAJ&pg=PA36&hl=de&source=gbs_selected_pages&cad=3#v=onepage&q&f=false
示例图片：
因此，在偶数页上，章节号位于左上角的灰色框中。后面是章节名称。与此处的示例不同，页眉线应延伸至整个页面，即该线应延伸至内边距。
在奇数页上，该部分应显示在右上角。同样，标题线应延伸至整个页面。
我目前的尝试：
\documentclass[a4paper, twoside]{scrbook}
\usepackage[english]{babel}
\usepackage[utf8]{inputenc}
\usepackage{lmodern}
\usepackage{xcolor}
\usepackage[markcase=noupper,headsepline]{scrlayer-scrpage}
\automark[section]{chapter}
\automark*[subsection]{}
\renewcommand\chaptermarkformat{}
\usepackage{adjustbox}
\newcommand{\Graybox}{\noindent\adjustbox{minipage=[c]{\marginparwidth}\centering,height=8pt, bgcolor=gray}}
\lehead{%
\makebox[0pt][r]{%
{\Graybox{\color{white}\textsf{\thechapter}}}\hspace*{1em}}%
\leftmark
}
\rohead{\rightmark}
\setkomafont{pagehead}{\normalfont\sffamily}
\usepackage{blindtext}% dummy text
\begin{document}
\Blinddocument
\end{document}

使用以下 MWE（基于本书作者 Herbert Voss 的代码的版本），您可以使用scrlayer-scrpage而不是scrpage2来获得所需的布局。
您应该查看以下一些事项：
和
\newlength\fullwidth
\setlength\fullwidth{\paperwidth}
\addtolength\fullwidth{-1in}
\addtolength\fullwidth{-\oddsidemargin}% für die Kopflinie
\fullwidth标题行的长度计算为（右边距 + 文本宽度），其中
%\setheadwidth[\marginparsep]{textwithmarginpar} % <====================
%\KOMAoption{headwidth}{textwithmarginpar} % <==========================
\KOMAoption是headwidth设置。因为我们希望线到达纸张末端，我们不能使用textwithmarginpar，所以我们必须使用
\KOMAoption{headwidth}{\fullwidth:0mm} % <===========================
并且headsepline设置为
%\setheadsepline[\fullwidth]{0.8pt} % <================================
\KOMAoption{headsepline}{0.8pt} % <=====================================
使用以下 MWE
