我知道可以使用各种包来定制标题；其中最重要的是 fancyhdr。
在我的文档索引中，我希望索引的当前“主题”显示在标题中。这类似于在文档正文的标题中显示当前章节。
有人可以告诉我怎么做吗？
答案1
这将帮助你入门
步骤 1：您需要一个索引样式文件 - 将其放在与您的 tex 文件相同的文件夹中，但您可以指定它放在其他地方
将文件命名为（本例中）index_xstyle.ist
headings_flag 1
heading_prefix "{\\large\\sffamily\\bfseries "
heading_suffix "}\\nopagebreak\n"
delim_0 "} \\dotfill " % Provide right brace for level_0 items when they have page number:
delim_1 " \\dotfill "
delim_2 " \\dotfill "
item_x1 "} \n \\subitem " % Provide the right brace for level_0 items when they have no page number:
item_0 "\n \\item \\indexmark{"%added this with its usual default to mark it up
第 2 步：尝试此 mwe
如果使用 imakeidx 的其他功能（例如拆分索引），则使用 --shell-escape 进行编译
\documentclass[a4paper]{article}
\usepackage{imakeidx}
\usepackage{fancyhdr}
\usepackage{hyperref}
%You need to make an index style
\fancypagestyle{index}{%
\fancyhead{}
\fancyhead[RO,LE]{\rightmark -- \leftmark}
}
%You need a macro to use in your index style file to collect the index marks
\newcommand{\indexmark}[1]{#1\markboth{#1}{#1}}
%Set up your index (say to use your style on page 1 of index too if desired)
\indexsetup{level=\section*,toclevel=section,firstpagestyle=index}
%You need to tell it to use your style file
\makeindex[columns=2,title=Main index,intoc,options={-s index_xstyle.ist},]
