从目录中的链接中排除章节编号：非编号章节错误

Question

我使用 etoc从目录中的链接中排除章节编号。但是，当我插入未编号的附录部分时 — etoc 会添加一个句点：

我玩了一下代码，发现问题出\etocthenumber在\etocsetstyle{section}定义上（没有 etoc 就没有点）。有解决办法吗？

这里是 MWE：

\documentclass{article}

\usepackage{etoolbox}
\usepackage{xcolor}

% heading styles:
\usepackage{titlesec}
\titleformat{\section}
  {\color{teal}\large\sffamily}
  {\thetitle.\hspace{0.5cm}}
  {0cm}
  {}

\titleformat{\subsection}
  {\color{violet}\bfseries}
  {\hspace{0.75cm}\thetitle.\hspace{0.3cm}}
  {0cm}
  {}

\titleformat{\subsubsection}
  {\color{olive}\itshape}
  {\hspace{1.3cm}\thetitle.\hspace{0.3cm}}
  {0cm}
  {}

% ToC styles:
\usepackage[dotinlabels]{titletoc}
\contentsmargin{2.55em} % space for a page number

\titlecontents{section}
    [3.8em] % 1.5em + 2.3em
    {\vspace{0.3cm}\sffamily\bfseries\large}
    {\contentslabel{2.3em}}
    {\hspace*{-2.3em}}
    {\normalsize\normalfont\rmfamily\titlerule*[1pc]{.}\contentspage}
    [\vspace{0.1cm}]

\titlecontents{subsection}
    [5.2em] % 3.8em + 1.3em
    {\vspace{0.1cm}}
    {\contentslabel{1.4em}}
    {\hspace*{-1.4em}}
    {\titlerule*[1pc]{.}\contentspage}
    []

\titlecontents{subsubsection}
    [6.5em] % 5.2em + 1.3em
    {\vspace{0.1cm}}
    {\contentslabel{1.3em}}
    {\hspace*{-1.3em}}

（我也是排除目录中的章节编号）

Answer 1

正如评论中提到的那样，鉴于OP代码使用的其他软件包，最简单的补救措施可能是放弃使用埃托克。

以防某些用户etoc发现这个问题，我仍然提供这个答案来解释处理该问题的方法etoc：只需使用\etocifnumbered命令。
