我必须构建一个具有不同节级（以及目录）的文档结构，该结构具有特定的自定义“编号”，而不是默认的数学编号。例如，在列表环境中，节的开头应始终像罗马数字一样（使用“\Alph*.”执行的操作），子节的开头始终为“(\arabic*)”，段落的开头为“\alph*\alph*)”，等等。
我已经为此搜索了很多次，但要么在我之前没人需要这个，要么我错过了要搜索的正确标签。
有什么方法可以做到吗？
目录看起来应该是这样的：
A. Section
I. Subsection
II. Subsection
1) Subsubsection
a) Paragraph
2) Subsubsection
a) Paragraph
aa) Subparagraph
B. Section
I. Subsection
1) Subsubsection
答案1
为了在整个文档中获得这种行为，我们使用以下titlesec包：
\usepackage{titlesec}
\renewcommand{\thesection}{\Alph{section}}
\titleformat{\section}{\normalfont\Large\bfseries}{\thesection.}{1em}{}
\renewcommand{\thesubsection}{\Roman{subsection}}
\titleformat{\subsection}{\normalfont\large\bfseries}{\thesubsection.}{1em}{}
\renewcommand{\thesubsubsection}{\arabic{subsubsection}}
\titleformat{\subsubsection}{\normalfont\normalsize\bfseries}{\thesubsubsection)}{1em}{}
\renewcommand{\theparagraph}{\alph{paragraph}}
\titleformat{\paragraph}[runin]{\normalfont\normalsize\bfseries}{\theparagraph)}{1em}{}
\renewcommand{\thesubparagraph}{\alph{subparagraph}\alph{subparagraph}}
\titleformat{\subparagraph}[runin]{\normalfont\normalsize\bfseries}{\thesubparagraph)}{1em}{}
对于目录，我们使用tocloft包进行定制：
\usepackage{tocloft}
\renewcommand{\cftsecaftersnum}{.}
\renewcommand{\cftsubsecaftersnum}{.}
\renewcommand{\cftsubsubsecaftersnum}{)}
\renewcommand{\cftparaaftersnum}{)}
\renewcommand{\cftsubparaaftersnum}{)}
\setlength{\cftsecnumwidth}{1.8em}
\setlength{\cftsubsecnumwidth}{2.3em}
\setlength{\cftsubsubsecnumwidth}{1.8em}
\setlength{\cftparanumwidth}{1.8em}
\setlength{\cftsubparanumwidth}{2.2em}
\setlength{\cftsecindent}{0em}
\setlength{\cftsubsecindent}{1.8em}
\setlength{\cftsubsubsecindent}{4.1em}
\setlength{\cftparaindent}{5.9em}
\setlength{\cftsubparaindent}{7.7em}
因此，这个 MWE
\documentclass{article}
\setcounter{secnumdepth}{5}
\setcounter{tocdepth}{5}
\usepackage{titlesec}
\renewcommand{\thesection}{\Alph{section}}
\titleformat{\section}{\normalfont\Large\bfseries}{\thesection.}{1em}{}
\renewcommand{\thesubsection}{\Roman{subsection}}
\titleformat{\subsection}{\normalfont\large\bfseries}{\thesubsection.}{1em}{}
\renewcommand{\thesubsubsection}{\arabic{subsubsection}}
\titleformat{\subsubsection}{\normalfont\normalsize\bfseries}{\thesubsubsection)}{1em}{}
\renewcommand{\theparagraph}{\alph{paragraph}}
\titleformat{\paragraph}[runin]{\normalfont\normalsize\bfseries}{\theparagraph)}{1em}{}
\renewcommand{\thesubparagraph}{\alph{subparagraph}\alph{subparagraph}}
\titleformat{\subparagraph}[runin]{\normalfont\normalsize\bfseries}{\thesubparagraph)}{1em}{}
\usepackage{tocloft}
\renewcommand{\cftsecaftersnum}{.}
\renewcommand{\cftsubsecaftersnum}{.}
\renewcommand{\cftsubsubsecaftersnum}{)}
\renewcommand{\cftparaaftersnum}{)}
\renewcommand{\cftsubparaaftersnum}{)}
\setlength{\cftsecnumwidth}{1.8em}
\setlength{\cftsubsecnumwidth}{2.3em}
\setlength{\cftsubsubsecnumwidth}{1.8em}
\setlength{\cftparanumwidth}{1.8em}
\setlength{\cftsubparanumwidth}{2.2em}
\setlength{\cftsecindent}{0em}
\setlength{\cftsubsecindent}{1.8em}
\setlength{\cftsubsubsecindent}{4.1em}
\setlength{\cftparaindent}{5.9em}
\setlength{\cftsubparaindent}{7.7em}
\begin{document}
\tableofcontents
\bigskip\bigskip
\section{A section}
\subsection{A subsection}
\subsection{A subsection}
\subsubsection{A subsubsection}
\paragraph{A paragraph}
\subsubsection{A subsubsection}
\paragraph{A paragraph}
\subparagraph{A subparagraph}

得出这个结果
