从目录中排除标题为空的部分

Question

我从\section 标题为空。在第一段旁边显示数字，我使用\section{}空标题，这将用数字标记该部分的第一段。这对于我的用例来说是完美的，但是：

如何从目录中排除标题为空的部分？

到目前为止我得到的信息是这样的：

\documentclass{report}
\usepackage[a4paper, margin=1.3in]{geometry}

\usepackage{etoolbox}
\usepackage[explicit]{titlesec}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% Set section numbers in the margin and center the chapter headings
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\setcounter{secnumdepth}{5}
\renewcommand\thesection{\arabic{section}}

% this length controls the hanging indent for titles
% change the value according to your needs
\newlength\titleindent
\setlength\titleindent{1.35cm}

\titleformat{\chapter}[block]
  {\normalfont\huge\bfseries\center}{}{0pt}{\hspace*{-\titleindent}#1}

    \else#1
    \fi
  }

\titleformat{\subsection}
  {\normalfont\large}{\llap{\parbox[t]{\titleindent}{\thesubsection\hfill}}}

作为条件测试的一部分，查看标题是否为空，您可以添加更改 ToC 深度所需的代码：

Answer 2

我并不是赞同你所做的，但事实就是如此。

您可以定义两个新命令，\emptysection并且\emptysubsection

\newcommand{\emptysection}[1]{%
    \begingroup\renewcommand\addcontentsline[3]{}%
    \section{#1}\endgroup%
}

\newcommand{\emptysubsection}[1]{%
    \begingroup\renewcommand\addcontentsline[3]{}%
    \subsection{#1}\endgroup%
}

当它们必须没有内容时，使用它们代替\section和。\subsection
