titlesec我使用带有（和mdframed，但带有 时也会发生这种情况）的样式部分格式tcolorbox，它会改变目录的样式。
我该如何将其恢复为正常样式？ （见下图和文件）

使用numberless密钥：此代码仅删除mdframed框
\titleformat{name=\section, numberless}%
{\normalfont\bfseries\itshape\fontsize{12.8}{14}\selectfont}{}{0pt}{#1}
但您也可以修改其他功能，还可以使用 修改未编号部分的间距\titlespacing{name=\section,numberless}{...}。
对于完全正常的 toc 格式（即正常的部分格式），使用
\titleformat{name=\section, numberless}
{\normalfont\Large\bfseries}{}{0pt}{#1}
