Answer 1

您可以使用titletoc与 (同一作者) 完美交互的包轻松完成此titlesec操作。要在目录中的每个部分前添加一些垂直空间，我们标记第一个部分并添加\vspace{.5\baselineskip}部分标题的“before”代码。将此值更改为您需要的任何值。

\documentclass{article}
\usepackage{titlesec}
\usepackage{titletoc}
\newif\iffirst\firsttrue % to flag first TOC entry
\titleformat{\section}[block]{\Large\bfseries\filcenter}{\S \thesection.}   {1em}{} 
\titleformat{\subsection}[block]{\large\bfseries\filcenter}{\S \thesubsection.}{1em}{}
\titlecontents{section}
              [0em] 
              {\iffirst\global\firstfalse\else\vspace{.5\baselineskip}\fi\bfseries}
              {}
              {\hspace*{-2.3em}}
              {\hfill\contentspage}
\begin{document}
\tableofcontents
\section{A section}
\subsection{A subsection}
\subsection{Another subsection}
\subsection{Another one}
\section{A second section}
\subsection{A subsection}
\end{document}

Answer 2

您还可以使用包tocbasic：

\documentclass{article}
\usepackage{titlesec}
\titleformat{\section}[block]{\Large\bfseries\filcenter}{\S \thesection.}   {1em}{} 
\titleformat{\subsection}[block]{\large\bfseries\filcenter}{\S \thesubsection.}{1em}{}

\usepackage{tocbasic}
\DeclareTOCStyleEntry[
  numwidth=0pt,
  entrynumberformat=\gobble
]{tocline}{section}
\newcommand\gobble[1]{}

\begin{document}
\tableofcontents
\section{A section}
\subsection{A subsection}
\subsection{Another subsection}
\subsection{Another one}
\section{A second section}
\subsection{A subsection}
\end{document}
