练习题在表格上自动编号

Question 1

有了包，etoc您就可以使用目录来实现这一点。

\etocname，\etocnumber是从文件中提取的\etocpage内容。这里我使用了，因为它已经包含章节编号。代码设置为练习的“名称”，写入文件时是章节编号。因此，如果需要，请提供此编号。etoc.toc\etocnumber.toc\etocname

使用 hyperref，这些内容就是链接（使用 hyperref 选项linktoc=all还可以链接页码）。

编辑 1：我添加了一些最后的润色来实现网格状排版。众所周知，这在 TeX 中总是有些困难，因为添加了所有行间胶水等。我用新的图像替换了输出的图像，并将链接着色以显示它们确实是链接。

请注意，这个看起来很花哨的更新与原始问题无关，它只是一个在所选的多列样式中确定输出外观的问题。（更新：注释掉的代码中标明了一种更简单的方法）。

编辑 2：我向宏添加了一个变体\exercisetotoc，这样就避免了为每个练习创建hyperref书签（显示在最终的 pdf 文件中）。根据具体情况，人们可能希望或不希望通过创建此类书签hyperref。不过，在这两种变体中，通过生成的列表中的练习编号etoc都正确超链接。

注意：使用来\tableofcontents显示etoc练习列表根本没有排除文档中的标准。假设我们有章节、节和小节。它们在linguo\tableofcontents中分别处于级别 0、1 和 2。然后etoc

\begin{document)
\etocsetlevel{exercise}{3} 
\setcounter{tocdepth}{2}
\tableofcontents
%....

显示一个完全标准的目录，包括章节（也可能是部分）、节和小节。在文档的后面

\setcounter{tocdepth}{1}
\etocsetlevel{exercise}{1} % 'exercise' `.toc` entries will be included
\etocsetlevel{section}{2}  % so we get rid of sections (subsections are already at level 2)
%...
%(the stuff below with \etocsetstyle{exercise} and \etocsetstyle{chapter}
%...
\tableofcontents % this table is the list of exercises as seen below
% see the code excerpts below to see how it is done

通过这种方式，我们可以etoc选择性地打印“列表”中的任何内容，所有这些都带有单身的 .toc文件...

\documentclass[a4paper,10pt]{book}
\usepackage[utf8x]{inputenc}
\usepackage{hyperref}
\hypersetup{colorlinks=true,linkcolor={blue}}  % <- UPDATE to show the links
\usepackage{etoc}


\newcount\exo % just for dummy generation of exercise numbers here

\def\exercisetotoc{\addcontentsline{toc}
         {exercise}
         {\protect\numberline{\theexerci}\thechapter}}

% actually as we will use only \etocnumber, we could have done here rather
% \def\exercisetotoc{\addcontentsline{toc}{exercise}{\theexerci}}
% and then we would have used below \etocname, rather than \etocnumber

% if one does NOT want hyperref to create bookmarks for each exercise, then 
% one should use:
%
% \makeatletter
% \def\exercisetotoc{\addtocontents {toc}{\protect\contentsline 
%       {exercise}{\theexerci }{\thepage }{\@currentHref }}} 
% \makeatother
%
% (here I am using the variant where below one would have used \etocname,
%  not \etocnumber )
%
% Note that the exercise numbers are still hyperlinked, the only difference
% is that they don't appear among the bookmarks of the PDF

\newtheorem{exerci}{\Large \bfseries}[chapter] 
\newenvironment{exercise}{\begin{exerci}\exercisetotoc}{\end{exerci}}

\begin{document}\thispagestyle{empty}

% setting up exercise for use with etoc 
\etocsetlevel{exercise}{1}

\etocsetstyle{exercise}
{}
{}
{\noindent\etocnumber\strut\leaders\etoctoclineleaders\hfill\etocpage\par}
{\pagebreak[2]\vskip\baselineskip}

% UPDATE FOR GRID LIKE LOOK:
% the following is to ensure "grid-like" typesetting, also with the chapter
% headings in the list (which are done with `\large' size hence upset 
% the line spacings)
% (it is assumed here that the chapter name fits on one or two 
% column-width lines, else the code would need some additions)
%
% or, one can just say \etocsetlevel{chapter}{2} to not have these chapter 
% headings included. Or, one can just be happy with the way `etoc` by default 
% typesets these headings in the TOC, which here however would lead to a 
% somewhat "ragged" look of the columns

\newbox\chapbox
\etocsetstyle{chapter}
{}
{}
{\setbox\chapbox=\vtop{\bfseries        % .5em would be better than 1ex here
        \noindent\strut\large\etocnumber\hskip1ex\etocname\par}%
\unvcopy\chapbox\nointerlineskip
\kern-\ht\chapbox\kern-\dp\chapbox\kern3\baselineskip\nopagebreak[3]}
{}

% update: the following would be a much simpler way to get the grid-like 
% typesetting, but the chapter titles might be a bit cramped as the 
% baselineskip is kept equal to the ones for `normalsize`, not `large`

%\etocsetstyle{chapter}
%{}
%{}
%{\noindent\strut{\bfseries\large\etocnumber\hskip.5em\etocname}\par
% \vskip\baselineskip}
%{}
