我正在使用 LaTeX 编写自己的课程，但在创建目录时遇到了困难。我完全不懂 LaTeX，但出于设计要求，我决定使用自定义课程。
以下是该课程的相关部分：
\RequirePackage{contour}
\RequirePackage{etoolbox}
\RequirePackage{tocloft}
\newcounter{ChapterCounter}
\newcounter{CurrentChapNum}
\setcounter{CurrentChapNum}{0}
\newenvironment{chapter}[2]
{
\thispagestyle{empty}
\refstepcounter{ChapterCounter}
\ifnum\value{ChapterCounter}=\value{CurrentChapNum}
% nop
\else
\setcounter{CurrentChapNum}{\value{ChapterCounter}}
\fi
% Write to ToC
\addcontentsline{toc}{chapter}%
{\protect\numberline{\theChapterCounter}#1}%
% \cftaddtitleline{toc}{section}{Topic 1}{}
}
{
% Irrelevant details omitted here for simplicity
}
\makeatletter
\newcommand{\tableofcontents}{
Table of Contents
\@starttoc{toc}%
}
\makeatother
如您所见，我正在定义自己的chapter环境。有一个章节计数器（实际上是两个，我敢打赌可能会更好，但这不是这里的问题），我将章节标题添加到 ToC 文件中。我还定义了tableofcontents只需写入标题（要格式化）并调用@starttoc。到目前为止一切顺利。这是主文件：
\documentclass{whitepaper}
\begin{document}
\tableofcontents
\chapter{Chapter 1}{Description for this chapter}
\chapter{Chapter 2}{Description for this chapter}
\chapter{Chapter 3}{Description for this chapter}
\end{document}
布局很简单。我只输入三个空白章节，标题分别为Chapter 1、Chapter 2和Chapter 3，所有章节的描述都相同。
一切似乎都正常，我得到了以下输出：
根据我的解释，每行都有一个编号，后面是章节名称（包括编号），然后是页码。因此，忽略所有空格，您将获得：
1 Chapter 1 .......... 1
2 Chapter 2 .......... 1
3 Chapter 3 .......... 1
格式很奇怪，我还没搞清楚空格从何而来，尤其是第一个换行符。\newline在第三个参数的末尾添加一个\addcontentsline会产生完全相同的结果，尽管我原本以为它会换行。如下所示：
\addcontentsline{toc}{chapter}%
{
\protect\numberline{\theChapterCounter}#1
\newline
}%
我明白这\addcontentsline为我添加了内容，我在其他地方读到的内容\cftaddtitleline应该很方便。我\addcontentsline用以下内容替换了：
\cftaddtitleline{toc}{chapter}{Chapter #1}{}
我收到以下错误：
! 未定义的控制序列。\chapter ...r }#1 \newline }\par \cftaddtitleline {toc}{chapter}{Chapter #1}{} l.43 ...r{Chapter 1}{本章说明} 错误消息顶行末尾的控制序列从未被 \def'ed。如果您拼错了它（例如，
\hobx'), typeI' 和正确的拼写（例如，`I\hbox'）。否则继续，我会忘记未定义的内容。! 未定义的控制序列。\chapter ...r }#1 \newline }\par \cftaddtitleline {toc}{chapter}{Chapter #1}{} l.44 ...r{Chapter 2}{Description for this chapter} 错误消息顶行末尾的控制序列从未被 \def'ed。如果您拼错了它（例如，

\hobx'), typeI' 和正确的拼写（例如，`I\hbox'）。否则继续，我会忘记未定义的内容。
我想知道的是如何使用上述命令或其他命令正确输出和格式化目录。

答案1
成功了！我用没有注释的内容替换了注释的内容：
% Write to ToC
% \addcontentsline{toc}{chapter}%
% {
% \theChapterCounter #1
% \newline
% }%
\addtocontents{toc}
{
\unexpanded{\unexpanded{\twodigits}}{\theChapterCounter}
#1
\newline
}
