scrbook 的 \subsubsubsection

tag-icon • tag-icon sectioning koma-script
scrbook 的 \subsubsubsection

为什么 \subsubsubsection 对 \documentclass{scrbook} 不起作用以及我该如何强制使用它？

有一个 MWE：

\documentclass{scrbook}
\setcounter{secnumdepth}{3}
\begin{document}
\chapter{Chapter}
\section{Section}
\subsection{Subsection}
\subsubsection{Subsubsection}
\subsubsubsection{Subsubsubsection}
\end{document}

使用此 MWE 会出现错误：“未定义的控制序列 \subsubsubsection”，并且 pdf 如下所示：

但是我需要最后一行“1.1.1.1.1. Subsubsubsection”。

答案1

更新（需要 KOMA-Script 版本 3.26b）

下面的原始答案仍然是正确的。但是有新的命令\RedeclareSectionCommands、新的选项runin和afterindent。并且使用为新的部分级别预定义了一些选项style=section。

建议 1：将新部分级别声明subsubsubsection为显示标题

\documentclass{scrbook}

\DeclareNewSectionCommand[
  style=section,
  counterwithin=subsubsection,
  afterskip=1.5ex plus .2ex,
  beforeskip=3.25ex plus 1ex minus .2ex,
  afterindent=false,
  level=\paragraphnumdepth,
  tocindent=10em,
  tocnumwidth=5em
]{subsubsubsection}
\setcounter{secnumdepth}{\subsubsubsectionnumdepth}
\setcounter{tocdepth}{\subparagraphtocdepth}

\RedeclareSectionCommands[
  level=\numexpr\subsubsubsectionnumdepth+1\relax,
  toclevel=\numexpr\subsubsubsectiontocdepth+1\relax,
  increaselevel
]{paragraph,subparagraph}
\RedeclareSectionCommand[
  counterwithin=subsubsubsection,
  tocindent=12em,
  tocnumwidth=6em
]{paragraph}
\RedeclareSectionCommand[
  tocindent=14em,
  tocnumwidth=7em
]{subparagraph}

\usepackage{lipsum}% only for dummy text
\begin{document}
\tableofcontents
\chapter{Chapter}
\section{Section}
\subsection{Subsection}
\subsubsection{Subsubsection}
\subsubsubsection{Subsubsubsection}
\lipsum[1-2]
\end{document}

建议2：重新定义paragraph为显示标题：

\documentclass{scrbook}

\RedeclareSectionCommand[
  afterskip=1.5ex plus .2ex,
  afterindent=false
]{paragraph}
\setcounter{secnumdepth}{\paragraphnumdepth}
\setcounter{tocdepth}{\paragraphtocdepth}

\usepackage{lipsum}% dummy text
\begin{document}
\tableofcontents
\chapter{Chapter}
\section{Section}
\subsection{Subsection}
\subsubsection{Subsubsection}
\paragraph{Paragraph}
\lipsum[1-2]
\end{document}

原始答案

您可以声明一个新的部分级别subsubsubsection。但随后您必须重新声明paragraph并subparagraph调整其级别等：

\documentclass{scrbook}

\DeclareNewSectionCommand[
  style=section,
  counterwithin=subsubsection,
  font=\normalsize,
  afterskip=1.5ex plus .2ex,
  beforeskip=-3.25ex plus -1ex minus -.2ex,
  indent=0pt,
  level=4,
  tocstyle=section,
  toclevel=4,
  tocindent=10em,
  tocnumwidth=5em
]{subsubsubsection}
\setcounter{secnumdepth}{\subsubsubsectionnumdepth}
\setcounter{tocdepth}{\subsubsubsectiontocdepth}

\RedeclareSectionCommand[
  level=5,
  counterwithin=subsubsubsection,
  toclevel=5,
  tocindent=12em,
  tocnumwidth=6em
]{paragraph}
\RedeclareSectionCommand[
  level=6,
  toclevel=6,
  tocindent=14em,
  tocnumwidth=7em
]{subparagraph}

\usepackage{lipsum}% only for dummy text
\begin{document}
\tableofcontents
\chapter{Chapter}
\section{Section}
\subsection{Subsection}
\subsubsection{Subsubsection}
\subsubsubsection{Subsubsubsection}
\lipsum[1-2]
\end{document}

如果不使用\paragraph作为 runin 标题，则可以paragraph使用正值重新声明节级别afterskip：

\documentclass{scrbook}

\RedeclareSectionCommand[
  afterskip=1.5ex plus .2ex,
  beforeskip=-3.25ex plus -1ex minus -.2ex
]{paragraph}
\setcounter{secnumdepth}{\paragraphnumdepth}
\setcounter{tocdepth}{\paragraphtocdepth}

\usepackage{lipsum}% dummy text
\begin{document}
\tableofcontents
\chapter{Chapter}
\section{Section}
\subsection{Subsection}
\subsubsection{Subsubsection}
\paragraph{Paragraph}
\lipsum[1-2]
\end{document}

答案2

最简单的方法是使用\paragraph并重新定义其格式：

\documentclass{scrbook}
\setcounter{secnumdepth}{5}

\RedeclareSectionCommand[
    counterwithin=subsubsection,
    toclinefill=\hfill,
    tocindent=3.5ex,
    tocnumwidth=1ex,
    tocdynnumwidth=true, 
    tocraggedentrytext=true,
    tocentryformat=\fontintoc\itshape,
    tocpagenumberformat=\fontintoc,
    beforeskip=10pt,%
    afterskip=1pt,
    font=\normalfont\itshape
    ]{paragraph}



    \begin{document}

\chapter{Chapter}
\section{Section}
\subsection{Subsection}
\subsubsection{Subsubsection}
\paragraph{Subsubsubsection}
\end{document}

答案3

如果您想保留\paragraph原样\subparagraph，那么您只需要新的级别编号，然后可以定义\subsubsubsection：

\documentclass{scrbook}
\RedeclareSectionCommand[level=6,toclevel=6]{subparagraph}
\RedeclareSectionCommand[level=5,toclevel=5]{paragraph}    
\DeclareSectionCommand[
  style=section,
  counterwithin=subsubsection,
  font=\normalsize,
  afterskip=1ex plus .2ex,
  beforeskip=-3.25ex plus -1ex,
  indent=0pt,
  level=4,
  tocstyle=section,
  toclevel=4,
  tocindent=10em,
  tocnumwidth=5em
]{subsubsubsection}

\setcounter{secnumdepth}{\subsubsubsectionnumdepth}
\setcounter{tocdepth}{\subsubsubsectiontocdepth}

\usepackage{lipsum}% only for dummy text
\begin{document}
    \tableofcontents
    \chapter{Chapter}
    \section{Section}
    \subsection{Subsection}
    \subsubsection{Subsubsection}
    \subsubsubsection{Subsubsubsection}
    \lipsum[1-2]
\paragraph{foo} \lipsum[1]
\subparagraph{bar} \lipsum[1]
\end{document}
