在 kaobook 类模板中，我已成功添加了子小节；但我该怎么做才能在 kaobook 侧目录中显示子小节？ 
%\setcounter{secnumdepth}{\kao@secnumdepth} % Set section numbering 
%depth
\setcounter{secnumdepth}{3}
\counterwithin*{sidenote}{chapter} % Uncomment to reset the sidenote counter at each chapter
%\counterwithout{sidenote}{chapter} % Uncomment to have one sidenote counter for the whole document

侧目录

答案1

当使用 ToC 边距时，该类kaobook不会定义子小节的条目。要做到这一点，需要重新定义相当长的\magintoc命令。

（1） \margintoc将在边距中插入本地目录。您可以使用可选参数将其向上或向下移动。例如，\margintoc[-0.6cm]与文本对齐

（2）要抑制特定本地目录的子部分，请使用

\etocsetnexttocdepth{2}
\setcounter{margintocdepth}{2}% 
\margintoc

C

% !TeX TS-program = pdflatex
