我要出版的书中有很多小章节，所以我改变了目录的外观。我对结果很满意，只是我想添加一条线来在视觉上将目录与章节分开mainmatter。frontmatter左边backmatter是我现在拥有的，但右边是我想要的。

和index_style.ist：
headings_flag 1
heading_prefix "\n\\raggedright\\large\\sffamily\\normalfont%
\\noindent\\textbf{"heading_suffix "}\\par\\nopagebreak\n"
item_0 "\n \\item \\small "
delim_0 " \\Dotfill "
delim_1 " \\Dotfill "
delim_2 " \\Dotfill "
和index_style2.ist：
item_0 "\n \\item \\small "
delim_0 " \\Dotfill "
delim_1 " \\Dotfill "
delim_2 " \\Dotfill "
答案1
您可以使用该命令\addtocontents{toc}{...}在文档写入时将任意代码添加到 .toc 文件的某个位置。
在您的例子中，我可能会定义一个可以重复使用的命令。使用类似于您建议的代码来生成规则并将其居中，这可能是这样的：
\newcommand{\inserttocseparator}{%
\addtocontents{toc}{\begin{center}\rule{.8\textwidth}{0.5pt}\end{center}}
}
然后，您可以\inserttocseparator在文档中与目录中要插入行的位置相对应的位置使用该命令。正如您所描述的那样，这可能紧跟在\mainmatterand之后\backmatter：
\mainmatter\inserttocseparator
和
\backmatter\inserttocseparator
结果如下：
这是个人喜好问题，但center环境产生的线上方和下方的间隙可能有点太大。另一种选择可能是：
\newcommand{\inserttocseparator}{%
\addtocontents{toc}{\par\hspace*{0.1\textwidth}\rule{0.8\textwidth}{0.5pt}\par}
}
结果更加紧凑：
如果您想对其进行微调，您可以\vspace*在定义中使用命令等进行尝试。\inserttocseparator
