目录：多行条目的一致缩进

Question

就像问的那样这里，我希望多行条目的所有行根据标题缩进，如下所示：

但是，下面的 MWE 排版如下：

我怎样才能获得预期的结果，最好不使用其他文档类？保留这些包也是一个不错的选择，但如果titletoc不支持这种排版，其他包也可以！

分数维：

\documentclass[10pt,twoside,a4paper]{article}
\usepackage{titlesec,titletoc}

\renewcommand*\contentsname{Quick Answers}
\titleformat{\section}{\Large\bfseries}{
    \ifnum\thesection<10 Q 0\thesection
    \else Q \thesection \fi
}{0.5em}{}
\titlecontents{section}[0.5em]{}{
    \large \textbf{Q\contentsmargin{20pt}
        \ifnum\thecontentslabel<10 0\else\fi
        \thecontentslabel\enspace} }
    {\contentsmargin{20pt}\normalfont}{\titlerule*[1mm]{ $\cdot$}\contentspage}
    [\addvspace{-2pt}]

\begin{document}
\tableofcontents

\section{Answer 1}
\section{Answer 2-a \\ Answer 2-b}

\end{document}

Answer 1

用于\contentslabel[<format>]{<space>}内容标签并添加<space>到第一个可选参数中的缩进。请注意，您还必须避免使用虚假空格。

\documentclass[10pt,twoside,a4paper]{article}
\usepackage{titlesec,titletoc}

\renewcommand*\contentsname{Quick Answers}
\titleformat{\section}{\Large\bfseries}{% <- comment the line end to avoid a spurious space
    \ifnum\thesection<10 Q 0\thesection
    \else Q \thesection \fi
  }{0.5em}{}
\titlecontents{section}
  [4.5em]% indent (.5em) + label width (4em)
  {\contentsmargin{20pt}}
  {% <- comment the line end to avoid a spurious space
    \contentslabel[\large\textbf{Q
        \ifnum\thecontentslabel<10 0\else\fi
        \thecontentslabel\enspace}]{4em}% <- comment the line end to avoid a spurious space
  }
  {\normalfont}{\titlerule*[1mm]{ $\cdot$}\contentspage}
  [\addvspace{2pt}]% <- changed 

\begin{document}
\tableofcontents
\section{Answer 1}
\section{Answer 2-a \\ Answer 2-b}
\end{document}

Answer 2

我的做法与 esdd 略有不同，以下是我的解决方案：

\documentclass[10pt,twoside,a4paper]{article}
\usepackage{titlesec,titletoc}

\renewcommand*\contentsname{Quick Answers}
\titleformat{\section}{\Large\bfseries}{% <-- don't forget the percent sign!
   \ifnum\thesection<10 Q 0\thesection
   \else Q \thesection
   \fi
 }{0.5em}{}

\newlength{\contentslabelwidth}
\setlength{\contentslabelwidth}{3.5em}

\newcommand*{\myprintcontentslabel}{%
  \begingroup
  \normalfont\large\bfseries
  Q\ifnum\thecontentslabel<10 0\else\fi % always two figures
  \thecontentslabel
  \endgroup
}

\titlecontents{section}[\contentslabelwidth]{}{% <-- don't forget!
  \contentsmargin{20pt}%
  \llap{\makebox[\contentslabelwidth][l]{\myprintcontentslabel}}}%
  {\contentsmargin{20pt}\normalfont}%
  {\titlerule*[1mm]{ $\cdot$}\contentspage}
  [] % I removed the \addvspace{-2pt} here: it made the lines way too close to
     % each other.

\begin{document}
\tableofcontents

\section{Answer 1}
\section{Answer 2-a\\ Answer 2-b}

\end{document}

您有几个虚假的空间，要小心这些（参见代码中的注释）！
