如何获得带有插入标题的缩进小节？

Question

我尝试过以下方法：

\usepackage{titlesec}
\titleformat{\subsubsection}[runin]{\bfseries}{\thesubsubsection}{1em}{} 

但如果我\titleformat{\subsubsection}[runin]{\hspace{3em}\bfseries}{\thesubsubsection}{1em}{}这样做会引发错误

Answer 1

这对我有用：

\usepackage{titlesec}
\titleformat{\subsubsection}[runin]{\bfseries}{\thesubsubsection}{1em}{} 
\titlespacing{\subsubsection}
  {1em}% left
  {3.25ex plus 1ex minus .2ex}% before
  {1em}% after
