我有這樣的文件（MWE）：
\documentclass[10pt,twoside,final]{book}
\usepackage{xltxtra}
\usepackage{fontspec}
\usepackage{fancyhdr}
\usepackage{titlesec}
\usepackage[hang,flushmargin]{footmisc}
\usepackage[titles]{tocloft}
\usepackage[absolute]{textpos}
\usepackage[initsep=16pt,unbalanced=false]{idxlayout}
\usepackage{index}
\newindex{default}{idx}{ind}{First index}
\begin{document}
\chapter{First}
Lorem ipsum \index{Lorem@ipsum} et dolorem.
End of first chapter.
\printindex
\end{document}
且索引標頭與其他標頭不同。
我很清楚，我可以以某種方式使用idxlayout（也許是自己的樣式文件）。但當我嘗試時，我總是失敗。

如文件第 2.3 節所述idxlayout，index必須在 之前載入套件idxlayout。使用正確的載入順序，索引標題的格式將像其他（未編號的）頂級分區標題（在您的 MWE：章節中）一樣。
