所有权长度规则

Question

标题右侧有一张图片。对于标题，我使用下划线\titlerule。

可以调整线条的长度吗？我希望线条只到文档的中间。

\documentclass[a4paper,10pt]{article}
\usepackage{titlesec}   

\titleformat{\subsection}{\Large\scshape\raggedright}{}{0em}{}
    [\titlerule]
\titlespacing{\subsection}{0pt}{3pt}{3pt}


\begin{document}    

\pagestyle{empty} % non-numbered pages

\begin{wrapfigure}{r}{0.28\textwidth}
  \begin{center}
    \includegraphics[width=0.23\textwidth]{picture}
  \end{center}

\end{wrapfigure}

\subsection{Personal Data}



\begin{tabular}{rl}
    \textsc{Date of Birth:} & xxx\\
    \textsc{Address:}   &  xxx\\
    \textsc{Phone:}     & xxx\\
    \textsc{email:}     & \href{mailto:xxx}{xxx}
\end{tabular}

\end{document}

Answer 1

\titlerule下面的示例修改了用于\titlewidth设置规则宽度的内部工作原理：

\documentclass{article}

\usepackage{titlesec}

\titleformat{\subsection}{\Large\scshape\raggedright}{}{0em}{}
  [\titlerule]
\titlespacing{\subsection}{0pt}{3pt}{3pt}

\let\oldtitleline\titleline
\renewcommand{\titleline}{\oldtitleline*}

\begin{document}    

\pagestyle{empty} % non-numbered pages

\setlength{\titlewidth}{0.5\textwidth}

\subsection{Personal Data}

\begin{tabular}{rl}
  \textsc{Date of Birth:} & xxx \\
  \textsc{Address:}       & xxx \\
  \textsc{Phone:}         & xxx \\
  \textsc{email:}         & xxx
\end{tabular}

\setlength{\titlewidth}{\textwidth}

\subsection{Personal Data}

\begin{tabular}{rl}
  \textsc{Date of Birth:} & xxx \\
  \textsc{Address:}       & xxx \\
  \textsc{Phone:}         & xxx \\
  \textsc{email:}         & xxx
\end{tabular}

\end{document}
