错误的 toc 小写标题

Question

接下来，除了最后一页之外，目录标题都是错误的，我找不到解决方案。我一直试图修改\tableofcontents以及\toc@heading命令，但没有成功。

\documentclass[12pt]{book}
\usepackage[left=3.8cm,right=3.8cm,top=10cm,bottom=10cm,letterpaper]{geometry}
\usepackage{kpfonts}        
\DeclareRobustCommand{\capsspacing}[1]{\textsc{\MakeLowercase{#1}}}
\usepackage[linktocpage=true]{hyperref}              
\begin{document}
\tableofcontents
\markboth{\capsspacing{\contentsname}}{\capsspacing{\contentsname}}
\chapter{title}\section{title}\section{title}\section{title}\section{title}\section{title}\section{title}
\chapter{title}\section{title}\section{title}\section{title}\section{title}\section{title}\section{title}
\chapter{title}\section{title}\section{title}\section{title}\section{title}\section{title}\section{title}
\end{document}

所有目录页的目录标题都应该是小写字母。

为了获得所需的结果，您可以\tableofcontents按照以下方式重新定义以book.cls更改标记：

\documentclass[12pt]{book}
\usepackage[left=3.8cm,right=3.8cm,paperheight=10cm,top=2cm,bottom=2cm]{geometry}
\usepackage{kpfonts}  

\DeclareRobustCommand{\capsspacing}[1]{\textsc{\MakeLowercase{#1}}}
\DeclareRobustCommand{\capsspacingb}{\scshape\MakeLowercase}

\usepackage[linktocpage=true]{hyperref}             
\usepackage[titles]{tocloft}

% chapters
\renewcommand{\cftchappresnum}{\normalfont}%
\renewcommand{\cftchapfont}{\capsspacingb}%
\renewcommand{\cftchappagefont}{\normalfont}%      

\makeatletter
\renewcommand\tableofcontents{%
    \if@twocolumn
      \@restonecoltrue\onecolumn
    \else
      \@restonecolfalse
    \fi
    \chapter*{\contentsname
        \@mkboth{%
           \scshape\MakeLowercase{\contentsname}}{\scshape\MakeLowercase{\contentsname}}}%
    \@starttoc{toc}%
    \if@restonecol\twocolumn\fi
    }
\makeatother      


\begin{document}
\tableofcontents
\chapter{title}\section{title}\section{title}\section{title}\section{title}\section{title}\section{title}
\chapter{title}\section{title}\section{title}\section{title}\section{title}\section{title}\section{title}
\chapter{title}\section{title}\section{title}\section{title}\section{title}\section{title}\section{title}
\end{document}

使用etoolbox包来修补\tableofcontents，代码简化：

\documentclass[12pt]{book}
\usepackage[left=3.8cm,right=3.8cm,paperheight=10cm,top=2cm,bottom=2cm]{geometry}
\usepackage{kpfonts}  
\usepackage{etoolbox}  

\patchcmd{\tableofcontents}{\MakeUppercase\contentsname}{\scshape\MakeLowercase{\contentsname}}{}{}
\patchcmd{\tableofcontents}{\MakeUppercase\contentsname}{\scshape\MakeLowercase{\contentsname}}{}{}

\DeclareRobustCommand{\capsspacing}[1]{\textsc{\MakeLowercase{#1}}}
\DeclareRobustCommand{\capsspacingb}{\scshape\MakeLowercase}

\usepackage[linktocpage=true]{hyperref}             
\usepackage[titles]{tocloft}

% chapters
\renewcommand{\cftchappresnum}{\normalfont}%
\renewcommand{\cftchapfont}{\capsspacingb}%
\renewcommand{\cftchappagefont}{\normalfont}%      

\begin{document}
\tableofcontents

\chapter{title}\section{title}\section{title}\section{title}\section{title}\section{title}\section{title}
\chapter{title}\section{title}\section{title}\section{title}\section{title}\section{title}\section{title}
\chapter{title}\section{title}\section{title}\section{title}\section{title}\section{title}\section{title}
\end{document}
