我正在排版一本有章节的书。使用 TeXShop。使用 imakeidx。我希望目录中的索引不带章节编号。现在一切都很好，只是我得到的不是索引顶部的标题“索引”，而是
第四部分
指数
在打印索引时，标题是指数在偶数页上，并且指数奇数。
这是我的主要文件（我省略了我认为不相关的内容。这应该运行并显示第一个问题）

\mychap
\section{Verrocchio's non-figural sculptures}
Sample text with endnote\endnote{This would be an endnote} and an index entry\index{Entry, index}.
}
\newpage
\subsection{Picture credits for Section IV}
\fontfamily{cmr}\selectfont{
Stand-in for picture credit.
}
\theendnotes
答案1
为了解决第一个问题，您可以像之前所做的那样再添加一个\titleformat，\printindex例如\mychap：
\titleformat{\chapter}[display]{\normalfont\Huge\bfseries}{0}{0pt}{##1}
第二个问题是由于\nouppercase您对页面样式的定义MyStyle。因此恕我直言，您也需要更改它，例如，对于INDEX奇数页和偶数页：
\fancypagestyle{MyBackStyle}{%
\fancyhead{} %Clean headers
\fancyhead[RO]{\slshape\rightmark}%
\fancyhead[LE]{\leftmark}%
\renewcommand{\chaptermark}%[1]{\markboth{\thechapter. {\slshape{##1}}}{}}
}
全部一起：
\begin{filecontents*}{Stack-Part-IV.tex}
\fontfamily{ppl}\selectfont{
\mychap
\section{Verrocchio's non-figural sculptures}
Sample text with endnote\endnote{This would be an endnote} and an index entry\index{Entry, index}.
}
\newpage
\subsection{Picture credits for Section IV}
\fontfamily{cmr}\selectfont{
Stand-in for picture credit.
}
\theendnotes
\end{filecontents*}
