减少目录中部分标题前的垂直空间

Question

如何减少目录中部分标题前的垂直空间？

以下是我所拥有的与标题及其目录条目相关的内容（我认为）：

\documentclass{article}

\usepackage{titletoc}

\makeatletter
\def\@part[#1]#2{%
    \ifnum \c@secnumdepth >\m@ne
      \refstepcounter{part}%
      \addcontentsline{toc}{part}{\thepart\hspace{1em}#1}%
    \else
      \addcontentsline{toc}{part}{#1}%
    \fi
    {\parindent \z@
     \interlinepenalty \@M
     \normalfont
     \ifnum \c@secnumdepth >\m@ne
       \Large\bfseries\hfil\partname~\thepart\hfil
       \par\nobreak
     \fi
     \huge\bfseries\sffamily\raggedleft #2%
     \markboth{}{}\par}%
    \nobreak
    \vskip 3ex
    \@afterheading}
\makeatother

\makeatletter
  \@addtoreset{section}{part}
  \@addtoreset{subsection}{section}
  \@addtoreset{subsubsection}{subsection}
\makeatother
\titlecontents{section}[1.8em]{}{\contentslabel{1.8em}}{\hspace*{0em}}{\titlerule*[1pc]{.}\contentspage}
\titlecontents{subsection}[4.65em]{}{\contentslabel{2.85em}}{\hspace*{0em}}{\titlerule*[1pc]{.}\contentspage}
\titlecontents{subsubsection}[8.35em]{}{\contentslabel{3.75em}}{\hspace*{0em}}{\titlerule*[1pc]{.}\contentspage}

\renewcommand*\thepart{\arabic{part}}
\renewcommand*\thesection{\thepart.\arabic{section}}


\begin{document}

\tableofcontents
\newpage

\part{sxsafawf}
\section{sasrvth}

\part{sxsafawf}
\section{sasrvth}

\end{document}

Answer 1

我认为您正在谈论的是\part而不是\chapter。

由于您正在重新定义\part命令，因此只需添加以下行

\addtocontents{toc}{\protect\vspace*{-15\p@}}

在重新定义中（-15\p@根据您的需要进行调整）。

梅威瑟：

\documentclass{article}

\usepackage{titletoc}

\makeatletter
\def\@part[#1]#2{%
    \ifnum \c@secnumdepth >\m@ne
      \refstepcounter{part}%
      \addtocontents{toc}{\protect\vspace*{-15\p@}}% <------------ added
      \addcontentsline{toc}{part}{\thepart\hspace{1em}#1}%
    \else
      \addtocontents{toc}{\protect\vspace*{-15\p@}}% <------------ added
      \addcontentsline{toc}{part}{#1}%
    \fi
    {\parindent \z@
     \interlinepenalty \@M
     \normalfont
     \ifnum \c@secnumdepth >\m@ne
       \Large\bfseries\hfil\partname~\thepart\hfil
       \par\nobreak
     \fi
     \huge\bfseries\sffamily\raggedleft #2%
     \markboth{}{}\par}%
    \nobreak
    \vskip 3ex
    \@afterheading}
\makeatother

\makeatletter
  \@addtoreset{section}{part}
  \@addtoreset{subsection}{section}
  \@addtoreset{subsubsection}{subsection}
\makeatother
\titlecontents{section}[1.8em]{}{\contentslabel{1.8em}}{\hspace*{0em}}{\titlerule*[1pc]{.}\contentspage}
\titlecontents{subsection}[4.65em]{}{\contentslabel{2.85em}}{\hspace*{0em}}{\titlerule*[1pc]{.}\contentspage}
\titlecontents{subsubsection}[8.35em]{}{\contentslabel{3.75em}}{\hspace*{0em}}{\titlerule*[1pc]{.}\contentspage}

\renewcommand*\thepart{\arabic{part}}
\renewcommand*\thesection{\thepart.\arabic{section}}


\begin{document}

\tableofcontents
\newpage

\part{sxsafawf}
\section{sasrvth}

\part{sxsafawf}
\section{sasrvth}

\end{document}

Answer 2

如果您不想指定\titlecontents{part}并且对类的默认排版感到满意article，那么修补原始\l@part命令就足够了，该titletoc命令调用\ttl@savel@part：

\documentclass{article}

\usepackage{titletoc}
\usepackage{etoolbox}

\makeatletter
\patchcmd{\ttl@savel@part}{2.25em}{1em}{}{} % <--- adjust to suit

\def\@part[#1]#2{%
    \ifnum \c@secnumdepth >\m@ne
      \refstepcounter{part}%
      \addcontentsline{toc}{part}{\thepart\hspace{1em}#1}%
    \else
      \addcontentsline{toc}{part}{#1}%
    \fi
    {\parindent \z@
     \interlinepenalty \@M
     \normalfont
     \ifnum \c@secnumdepth >\m@ne
       \Large\bfseries\hfil\partname~\thepart\hfil
       \par\nobreak
     \fi
     \huge\bfseries\sffamily\raggedleft #2%
     \markboth{}{}\par}%
    \nobreak
    \vskip 3ex
    \@afterheading}
\makeatother

\makeatletter
  \@addtoreset{section}{part}
  \@addtoreset{subsection}{section}
  \@addtoreset{subsubsection}{subsection}
\makeatother
\titlecontents{section}[1.8em]{}{\contentslabel{1.8em}}{\hspace*{0em}}{\titlerule*[1pc]{.}\contentspage}
\titlecontents{subsection}[4.65em]{}{\contentslabel{2.85em}}{\hspace*{0em}}{\titlerule*[1pc]{.}\contentspage}
\titlecontents{subsubsection}[8.35em]{}{\contentslabel{3.75em}}{\hspace*{0em}}{\titlerule*[1pc]{.}\contentspage}

\renewcommand*\thepart{\arabic{part}}
\renewcommand*\thesection{\thepart.\arabic{section}}


\begin{document}

\tableofcontents
\newpage

\part{sxsafawf}
\section{sasrvth}

\part{sxsafawf}
\section{sasrvth}

\end{document}

Answer 3

重新定义\part目录中的格式并给出间距参数就足够了。顺便说一下，写作

\@addtoreset{subsection}{section}
\@addtoreset{subsubsection}{subsection}

毫无用处 — — 这是默认设置。

有以下可能性：

\documentclass{article}

\usepackage{titletoc}

\makeatletter
\def\@part[#1]#2{%
    \ifnum \c@secnumdepth >\m@ne
      \refstepcounter{part}%
      \addcontentsline{toc}{part}{\thepart\hspace{1em}#1}%
    \else
      \addcontentsline{toc}{part}{#1}%
    \fi
    {\parindent \z@
     \interlinepenalty \@M
     \normalfont
     \ifnum \c@secnumdepth >\m@ne
       \Large\bfseries\hfil\partname~\thepart\hfil
       \par\nobreak
     \fi
     \huge\bfseries\sffamily\raggedleft #2%
     \markboth{}{}\par}%
    \nobreak
    \vskip 3ex
    \@afterheading}
\makeatother

\makeatletter
  \@addtoreset{section}{part}
  \@addtoreset{subsection}{section}
  \@addtoreset{subsubsection}{subsection}
\makeatother
\titlecontents{part}[0em]{\vspace{2ex}\bfseries}{\contentslabel{1.8em}}{\hspace*{0em}}{\titlerule*[1pc]{.}\contentspage}[\smallskip]
\titlecontents{section}[3.6em]{}{\contentslabel{1.8em}}{\hspace*{0em}}{\titlerule*[1pc]{.}\contentspage}
\titlecontents{subsection}[4.65em]{}{\contentslabel{2.85em}}{\hspace*{0em}}{\titlerule*[1pc]{.}\contentspage}
\titlecontents{subsubsection}[8.35em]{}{\contentslabel{3.75em}}{\hspace*{0em}}{\titlerule*[1pc]{.}\contentspage}

\renewcommand*\thepart{\arabic{part}}
\renewcommand*\thesection{\thepart.\arabic{section}}

\begin{document}

\tableofcontents
\newpage

\part{sxsafawf}
\section{sasrvth}

\section{another section}

\section{a third section}

\part{sxsafawf}
\section{sasrvth}

\end{document}
