我正在尝试创建一种花哨的论文风格，但我被困在了目录中。我采用了 Pluton 的想法如何使用 TikZ 自定义目录？但我收到一条错误信息
! Missing $ inserted. <inserted text> l.1 ...ter}{\numberline

我没有使用任何数学模式，所以我不明白这是从哪里来的。我的代码如下

我认为我确信花式篇章和精美的目录但我不知道如何找到它。有人知道发生了什么吗？
答案1
问题在于 for 的最后一个强制参数，\titlecontents其中chapter您使用的\;是一个仅限数学模式的空间，并且您试图在文本模式下使用它；将它们替换为文本模式空间。
我使用“％问题在这里”标记了下面有问题的行，这样您就可以轻松地看到问题出在哪里并可以应用必要的更正：
\titlecontents{chapter}[0pc]
{\addvspace{30pt}%
\begin{tikzpicture}[remember picture, overlay]%
\draw[fill=doc!30,draw=doc!30, rounded corners] (-4,-.1) rectangle (-1,.5);%
\pgftext[left,x=-3.7cm,y=0.2cm]{\color{white}\Large\scshape\bfseries chapter\ \thecontentslabel};%
\end{tikzpicture}\color{doc!40}\large\sc\bfseries}%
{}
{}
{\;\titlerule\;% the problem is here
\large\scshape\bfseries Page \thecontentspage
\begin{tikzpicture}[remember picture, overlay]
\draw[fill=doc!25,draw=doc!20, rounded corners=0pt] (2pt,0) rectangle (6,0.1pt);
\end{tikzpicture}}%
因为你不是自然地处于数学模式，而不是错误的
\;\titlerule\;
你可以使用
\enspace\titlerule\enspace
或者
\hspace*{6pt}\titlerule\hspace*{6pt}
更改6pt为适合您需要的长度。
