我想要自定义章节格式，如下所示：
\titleformat{\chapter}[display]
{\centering\normalfont\Huge\bfseries}
{}{0pt}
{\titlerule\vspace{1ex}\filcenter}
[\vspace{.75ex}{\titlerule}]
我发现目录的标题与章节的行为类似。是否可以将目录的标题设为默认样式，而将所有其他章节设为我的自定义样式（上面的代码）？
这是我的 MWE：
\documentclass[14pt,twoside]{extbook}
\usepackage[utf8]{inputenc}
\usepackage[main=czech,slovak]{babel}
\usepackage{xcolor}
\usepackage{nameref}
\usepackage{hyperref}
\hypersetup{
colorlinks = true,
linkbordercolor = {white},
linkcolor = {black},
breaklinks
}
\usepackage[hang,flushmargin]{footmisc}
\raggedbottom
\usepackage{titletoc}
%\usepackage{sectsty}
\addtolength{\textheight}{47mm}
\addtolength{\textwidth}{22mm}
\addtolength{\oddsidemargin}{-1mm}
\addtolength{\evensidemargin}{-15mm}
\addtolength{\topmargin}{-23mm}
\emergencystretch 1em
\usepackage[labelfont=bf]{caption}
\setlength{\parindent}{.7pt}

只需发出\titleformat命令后 \tableofcontents。
\documentclass{book}
\usepackage{titlesec}
\begin{document}
\tableofcontents
\titleformat{\chapter}[display]
{\centering\normalfont\Huge\bfseries}
{}{0pt}
{\titlerule\vspace{1ex}\filcenter}
[\vspace{.75ex}{\titlerule}]
\chapter{Foo}
\chapter{Bar}
\end{document}
