在文本中显示所有级别的章节编号，但不在目录中显示？

Question

我希望目录中的章节编号显示为

\renewcommand\thesection{\Roman{section}}
\renewcommand\thesubsection{\alph{subsection}}
\renewcommand\thesubsubsection{\arabic{subsubsection}}

但在文本中应该看到完整的编号：

\renewcommand\thesection{\Roman{section}}
\renewcommand\thesubsection{\Roman{section}.\alph{subsection}}
\renewcommand\thesubsubsection{\Roman{section}.\alph{subsection}.\arabic{subsubsection}}

使用 titlesec/titletoc 可以实现吗？

Answer 1

将目录中不需要的部分括在宏中，该宏通常仅定义为打印其内容，但是在文件中.aux为目录条目做注释时，它会被重新定义为吞噬其内容。

负责注释的宏\addtocontents已经做了类似的事情，通过重新定义\label和\index吞噬\glossary它们的参数；所以我们只需要在列表中添加另一个宏。

Answer 2

哦，我解决了。正在重新定义部分格式titleformat：

\documentclass{article}

\usepackage{xcolor}
\definecolor{Blue}{HTML}{2E3192}

% heading styles:
\usepackage{titlesec}
\titleformat{\section}
  {\color{teal}\large\sffamily}
  {\thetitle.\hspace{0.5cm}}
  {0cm}
  {}

\titleformat{\subsection}
  {\color{violet}\bfseries}
  {\renewcommand\thesubsection{\Roman{section}.\alph{subsection}}\hspace{0.75cm}\thetitle.\hspace{0.3cm}}
  {0cm}
  {}

\titleformat{\subsubsection}
  {\color{olive}\itshape}
  {\renewcommand\thesubsubsection{\Roman{section}.\alph{subsection}.\arabic{subsubsection}}\hspace{1.3cm}\thetitle.\hspace{0.3cm}}
  {0cm}
  {}

% ToC styles:
\usepackage[dotinlabels]{titletoc}
\contentsmargin{2.55em} % space for a page number

\titlecontents{section}
    [3.8em] % 1.5em + 2.3em
    {\vspace{0.3cm}\sffamily\bfseries\large}
    {\contentslabel{2.3em}}
    {\hspace*{-2.3em}}
    {\normalsize\normalfont\rmfamily\titlerule*[1pc]{.}\contentspage}
    [\vspace{0.1cm}]

\titlecontents{subsection}
    [5.2em] % 3.8em + 1.3em
    {\vspace{0.1cm}}
    {\contentslabel{1.4em}}
    {\hspace*{-1.4em}}
    {\titlerule*[1pc]{.}\contentspage}
    []

\titlecontents{subsubsection}
    [6.5em] % 5.2em + 1.3em
    {\vspace{0.1cm}}
    {\contentslabel{1.3em}}
    {\hspace*{-1.3em}}
    {\titlerule*[1pc]{.}\contentspage}
    []

\renewcommand\thesection{\Roman{section}}
\renewcommand\thesubsection{\alph{subsection}}
\renewcommand\thesubsubsection{\arabic{subsubsection}}

\usepackage{lipsum}

\begin{document}

\tableofcontents

\section{A section}\lipsum[1]
\subsection{A subsection}\lipsum[2-4]
\subsection{Another subsection}\lipsum[5-6]
\subsection{A subsection}\lipsum[7-8]
\subsection{Another subsection}\lipsum[9-10]
