子部分编号丢失

Question

当我设置子小节以便文本从标题开始运行时，子小节编号不会出现。添加命令以编号到深度 3 也无济于事。除了手动添加每个标签外，我还能做什么吗？

\documentclass{article}

\usepackage{titlesec}

%Styles for sections and (sub-)subsections
\titleformat*{\subsection}{\normalsize\itshape}
\titleformat{\subsubsection}[runin]{\normalsize\itshape}{}{0em}{}
\titleformat*{\paragraph}{\normalsize\itshape}

\titlespacing*{\section}{0pt}{18pt}{6pt plus 1pt minus 1pt}
\titlespacing*{\subsection}{0pt}{12pt}{0pt plus 1pt minus 1pt}

%Add dot after section numbers but not (sub-)subsection numbers
\usepackage{subfigure}
\usepackage[subfigure]{tocloft}
\titleformat{\section}
 {\normalfont\bfseries}{\thesection.}{0.5em}{}
\renewcommand\cftsecaftersnum{.} 
\renewcommand\thesection{\arabic{section}}
\renewcommand\thesubsection{\thesection.\arabic{subsection}}
\renewcommand{\thesubsubsection}{\thesubsection.\arabic{subsubsection}}

\setcounter{secnumdepth}{3}

\begin{document}

\section{Section}
This is the start of a section.

\subsection{Subsection}
This is the start of a subsection.

\subsubsection{Subsubsection}\label{3.1.1}

This is a subsubsection, but the number's missing.

\subsubsection{1.1.2\quad Another subsubsection}\label{3.1.2}
This is a subsubsection manually numbered to look roughly as it should. Why is the label for \S\ref{3.1.1} not showing?

\paragraph{Paragraph}
For completeness.

\end{document}

Answer 1

您的 似乎缺少一个参数\titleformat{\subsubsection}[runin]{\normalsize\itshape}{\thesubsubsection}{0.5em}{}。与 不同，\titleformat*{}必须手动将编号参数传递给它。
