我正在使用titletoc来为我的章节创建部分目录。我想将部分目录放在框中，以便框的宽度调整为目录的宽度 (a tcbox)。tcolorbox环境可以工作（但大小未调整），但根本tcbox不起作用。下面是一个说明我的问题的示例：
\documentclass[twoside,openright,titlepage,numbers=noenddot,
footinclude,cleardoublepage=empty,abstract=on,
BCOR=5mm,paper=a4,fontsize=12pt
]{scrreprt}
\usepackage[utf8]{inputenc}
\usepackage[french]{babel}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage{titletoc}
\usepackage{tcolorbox}
\titlecontents{lsection}
[1pc]
{\sffamily}
{\bfseries\scriptsize\contentslabel[\thechapter.\thecontentslabel]{2pc}}
{}
{\bfseries\scriptsize\contentspage}
[\addvspace{-3pt}]
\titlecontents{lsubsection}
[3pc]
{\sffamily}
{\scriptsize\contentslabel[\thechapter.\thecontentslabel]{2pc}}
{}
{\scriptsize\contentspage}
[\addvspace{-3pt}]
\begin{document}
\tableofcontents
\chapter{Chapter 1}
\startcontents[chapter]
\begin{tcolorbox}[colback=gray!10!white, colframe= gray!10!white,
title=Sommaire,coltitle=black]
\printcontents[chapter]{l}{1}{\setcounter{tocdepth}{2}}
\end{tcolorbox}
\tcbox[colback=gray!10!white, colframe= gray!10!white,
title=Sommaire,coltitle=black]{
\printcontents[chapter]{l}{1}{\setcounter{tocdepth}{2}}}
\section{Sec1}
\subsection{Subsec1}
Some text
\subsection{Subsec2}
Some text
\section{Sec2}
\end{document}

如果您将部分目录插入其中，它就可以工作\parbox。因此，我提出了一种解决方法：使用 (大约) 章节标题宽度的 \parbox。
\documentclass[twoside,openright,titlepage,numbers=noenddot,
footinclude,cleardoublepage=empty,abstract=on,
BCOR=5mm,paper=a4,fontsize=12pt]{scrreprt}
\usepackage[utf8]{inputenc}
\usepackage[french]{babel}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage{titletoc}
\usepackage{tcolorbox}
\usepackage{pbox}
\titlecontents{lsection}
[1pc]
{\sffamily}
{\bfseries\scriptsize\contentslabel[\thechapter.\thecontentslabel]{2pc}}
{}
{\hfill\bfseries\scriptsize\contentspage}
[\addvspace{-3pt}]
\titlecontents{lsubsection}
[3pc]
{\sffamily}
{\scriptsize\contentslabel[\thechapter.\thecontentslabel]{2pc}}
{}
{\scriptsize\contentspage}
[\addvspace{-3pt}]
\begin{document}
\tableofcontents
\chapter{Chapter 1}
\startcontents[chapter]
\tcbox[colback=gray!10!white, colframe= gray!10!white,
title=Sommaire,coltitle=black]{
\parbox{0.25\linewidth}{\printcontents[chapter]{l}{1}{\setcounter{tocdepth}{2}}}}
\section{Sec1}
\subsection{Subsec1}
Some text
\subsection{Subsec2}
Some text
\section{Sec2}
\end{document}
