用etoc宏包定制一个漂亮的目录样式

通常定制章节样式或者目录样式，采用的包最多的是titlesec和titletoc宏包，最近，又有了一个新的包etoc，其定制性上更进一步，推荐大家阅读其说明，试用试用！ 例如下面这一目录样式：用etoc宏包定制的代码如下：

\documentclass{book}
\usepackage{etoc}
\etocsetlevel{authors}{1}
\etocsetlevel{section}{2}
\etocsetlevel{subsection}{3}
\etocsettocdepth{section}
\newcommand{\authorstotoc}[1]{\etoctoccontentsline{authors}{#1}}

\newlength{\tocleft}
\setlength{\tocleft}{3cm}

\newlength{\tocsep}
\setlength{\tocsep}{2em}


\etocsetstyle{part}{}{}{{\bfseries\makebox[0pt][r]
                              {\partname\ \etocnumber\hspace{\tocsep}}%
                     \etocname\kern1em\relax\etocpage\par}\vspace{3ex}}{}

% to avoid possible line breaks between chapter (or part) name and page number
% replace \quad by \kern1em\relax

\etocsetstyle{chapter}{}{}{\etocifnumbered
                             {\makebox[0pt][r]
                               {\chaptername\ \etocnumber\hspace{\tocsep}}}
                             {\ifcase\TEMP
                              \def\TEMP{1}\or\def\TEMP{2}%
                              \makebox[0pt][r]
                                  {\parbox[t]{\dimexpr\tocleft-\tocsep\relax}
                                   {\raggedleft Introductory\\ \strut \chaptername}%
                                   \hspace{\tocsep}}\fi
                              }\textbf{\etocname\kern1em\relax\etocpage}\par
                             \etocifnumbered{}{\vspace{2ex}}}{}

\etocsetstyle{authors}{}{}{\etocname\par\vspace{1ex}}{\vspace{2ex}}

\etocsetstyle{section}{}{}{\makebox[0pt][r]{\etocnumber\hspace{\tocsep}}%
                           \etocname\kern1em\etocpage\par}{}

\etocsettocstyle {\noindent\sffamily{\LARGE \contentsname}\par
                  \thispagestyle{empty}%
                  \noindent\rule{\dimexpr\tocleft-\tocsep}{1pt}\par\vspace{3ex}%
                  \leftskip\tocleft\parindent0pt\def\TEMP{0}}{}
