我必须创建以下目录：
现在，我可以创建这个：
它是使用 titletoc 制作的，即我指定：
\titlecontents{section}[1em]{\normalfont \sffamily \bfseries}
{\thecontentslabel\enspace}
{}
{\titlerule*[1pc]{.}\quad\contentspage}[\vskip 4pt]
这只是我找到并稍作调整的一个例子。不幸的是，我现在无法弄清楚文档，它对我来说似乎太难了。所以如果有人能帮助我维护目录的默认布局并将编号也设为蓝色，我会非常高兴。我所说的默认布局是指删除上面一行代码后得到的布局：
这正是我需要的，但部分名称采用粗体无衬线字体。以下是整个文件：
\documentclass{article}
\usepackage{amsmath}
\usepackage{titlesec, titletoc}
\usepackage{amssymb}
\usepackage[utf8]{inputenc}
\usepackage{hyperref}
\titleformat{\section}
{\normalfont \Large \sffamily \bfseries}{\thesection}{1em}{}
\titleformat{\subsection}
{\normalfont \large \sffamily \bfseries}{\thesubsection}{1em}{}
\titlecontents{section}[1em]{\normalfont \sffamily \bfseries}
{\thecontentslabel\enspace}
{}
{\titlerule*[1pc]{.}\quad\contentspage}[\vskip 4pt]
\hypersetup{

\section{Mathematical Formulas}
\subsection*{equations}
As upcoming mathematician you should be able to type a formula as simple
as formula (1). The only difficulty should be constraint making use of \texttt{\textbackslash rlap}:
\begin{equation}
\hspace{10000pt minus 1fil} \int_0^x \frac{1}{t+1} \text{d}t = \ln (x+1) \qquad \qquad \text{for} \, x \in ] -1, \infty [ \hfilneg
\end{equation}
\subsection{sets}
Don’t check the formula to be correct, just type it:
\[\forall x, M,N,O: (x \in M \lor (x \in N \land x \in O) \longleftrightarrow (M \cup N) \times (M \cup O) \ni (x,x))\]
\subsection{function definition}
$\varphi: \mathbb{C \times N \rightarrow R}, (z,m) \mapsto (\text{Re}(z+i))^m \cdot m$ is a simple function with $\varphi(2,2) = 8$.
\subsection{linear equations}
