标题中的一些标题与数字不匹配。示例中的第 3 页就出现了这种情况。有什么解决办法或解决方法吗？
\documentclass[twoside]{report}
\usepackage[ansinew]{inputenc}
\usepackage{fancyhdr}
\usepackage{lipsum}
\pagestyle{fancy}
\renewcommand{\subsectionmark}[1]{\markright{ #1}}
\renewcommand{\sectionmark}[1]{\markright{ #1}}
\renewcommand{\chaptermark}[1]{\markright{ #1}}
\rfoot{}
\cfoot{}
\fancyhead[LO,RE]{\thesubsection \rightmark}
\fancyhead[RO,LE]{\thepage}
\renewcommand {\headrulewidth}{0pt}
\renewcommand {\footrulewidth}{0pt}
\setcounter{secnumdepth}{3}
\setcounter{tocdepth}{3}
\begin{document}
\chapter{Some chapter}
\section{Section I}

\subsection{Subsection}
\lipsum[1-2]
\section{Section II}
\lipsum[1-2]
\subsection{Subsection One}

\subsection{Subsection Two}
\lipsum[1-2]
\section{Section III}

章节编号必须与标题一起添加\markright。在页眉中添加已经太晚了。
编号由计数器控制secnumdepth。因此，示例还检查了的值，secnumdepth以避免在标题中给出数字，但在文本中没有给出数字的情况。
\documentclass[twoside]{report}
\usepackage[ansinew]{inputenc}
\usepackage{fancyhdr}
\usepackage{lipsum}
\pagestyle{fancy}
\renewcommand{\subsectionmark}[1]{%
\markright{%
\ifnum\value{secnumdepth}>1 %
\thesubsection~%
\fi
#1%
}%
}
\renewcommand{\sectionmark}[1]{%
\markright{%
\ifnum\value{secnumdepth}>0 %
\thesection~%
\fi
#1%
}%
}
\renewcommand{\chaptermark}[1]{%
\markright{%
\ifnum\value{secnumdepth}>-1 %
\thechapter~%
