KOMA 章节标题：编号章节和非编号章节的高度相同

Question

我已经使用 KOMA 选项格式化了章节标题，以使章节编号显示在章节标题上方。不幸的是，我不知道如何让两个章节名称以相同的高度开始。这张图片显示了我当前 MWE 的输出。也许有人可以帮助我解决这个问题。提前致谢！

\documentclass[
a4paper,
10pt,
listof=totoc,
bibliography=totoc,
twoside,
]{scrreprt}

\usepackage[no-math]{fontspec}
\PassOptionsToPackage{no-math}{fontspec}
\usepackage[showframe]{geometry}
\usepackage{blindtext}
\usepackage{footnotebackref}

\hypersetup{pdfpagelayout=TwoPageRight}
\setlength{\parindent}{0pt}

\KOMAoptions{chapterprefix=true}
\renewcommand{\raggedchapter}{\raggedleft}
\renewcommand{\chapapp}{}
\RedeclareSectionCommand[
    prefixfont = \bfseries\fontsize{50}{52}\selectfont,
    font = \Huge,
    beforeskip = 40pt,
    innerskip = 0pt,
    afterskip = 40pt,
]{chapter}


\begin{document}

\chapter*{Unnumbered Chapter} \addcontentsline{toc}{chapter}{Unnumbered Chapter}
\blindtext
\chapter{Numbered Chapter}
\blindtext

\end{document}

Answer 1

您可以重新定义\chapterlineswithprefixformat：

\documentclass[
  %a4paper,% default
  10pt,
  listof=totoc,
  bibliography=totoc,
  twoside
]{scrreprt}

\usepackage[no-math]{fontspec}
\usepackage[showframe]{geometry}
\usepackage{blindtext}
\usepackage{footnotebackref}

\hypersetup{pdfpagelayout=TwoPageRight}
%\setlength{\parindent}{0pt}% use class option parskip=half or parskip=full

\KOMAoptions{chapterprefix=true}
\renewcommand*{\raggedchapter}{\raggedleft}
\renewcommand*{\chapterformat}{\thechapter}
\RedeclareSectionCommand[
    prefixfont = \bfseries\fontsize{50}{52}\selectfont,
    font = \Huge,
    beforeskip = 40pt,
    innerskip = 0pt,
    afterskip = 40pt,
]{chapter}

\makeatletter
\renewcommand*\chapterlineswithprefixformat[3]{%
  \Ifstr{#1}{chapter}
    {\IfArgIsEmpty{#2}
      {{\usekomafont{#1prefix}{%
          \mbox{}%
          \setlength{\@tempskipa}{\csname scr@#1@innerskip\endcsname}\chapterheadmidvskip
        }}#3%
      }% unnumbered chapter headings
      {#2#3}% numbered chapter headings
    }
    {#2#3}% other headings using style=chapter
}
\makeatother

\begin{document}
\addchap{Unnumbered Chapter}% unnumbered chapter with ToC entry
\blindtext
\chapter{Numbered Chapter}
\blindtext
\end{document}
