新的小节定义重新定义了原始小节编号

Question

我使用包创建了新的部分（即“工作包”）和子部分（即“任务”）标题titlesec。两个标题的定义如下。

% Workpackage section
\titleclass{\WP}{straight}[\section]
\titleformat{\WP}{\normalfont\normalsize\bfseries}{}{0em}{Work Package \theWP :\,}
\titlespacing*{\WP}{0pt}{2.25ex plus 1ex minus .2ex}{1.5ex plus .2ex}
\newcounter{WP}
\renewcommand\theWP{\arabic{WP}}

% Task subsection
\newcounter{Taskr}
\renewcommand\theTaskr{\theWP.\arabic{Taskr}}
\titleclass{\Taskr}{straight}[\WP]
\titleformat{\Taskr}[runin]{\normalfont\normalsize\itshape}{}{0em}{Task \theTaskr :\,}
\titlespacing*{\Taskr}{0pt}{2.25ex plus 1ex minus .2ex}{1.5ex plus .2ex}
\numberwithin{Taskr}{WP}

但是，当我编译该文档时，普通的小节标题没有标题编号，例如：

1. Section
Subsection
Subsection
2. Section
Subsection
Workpackage 1
Task 1.1

代替

1. Section
1.1 Subsection
1.2 Subsection
2. Section
2.2 Subsection
Workpackage 1
Task 1.1

如何修改我的定义？MWE 粘贴在下面。

\documentclass{article}
\usepackage{amsmath}
\usepackage{titlesec}

% Workpackage section
\titleclass{\WP}{straight}[\section]
\titleformat{\WP}{\normalfont\normalsize\bfseries}{}{0em}{Work Package \theWP :\,}
\titlespacing*{\WP}{0pt}{2.25ex plus 1ex minus .2ex}{1.5ex plus .2ex}
\newcounter{WP}
\renewcommand\theWP{\arabic{WP}}

% Task subsection
\newcounter{Taskr}
\renewcommand\theTaskr{\theWP.\arabic{Taskr}}
\titleclass{\Taskr}{straight}[\WP]
\titleformat{\Taskr}[runin]{\normalfont\normalsize\itshape}{}{0em}{Task \theTaskr :\,}
\titlespacing*{\Taskr}{0pt}{2.25ex plus 1ex minus .2ex}{1.5ex plus .2ex}
\numberwithin{Taskr}{WP}

% Don't want to include WP and Tasks into bookmarks and TOC
\makeatletter
  \def\toclevel@WP{6}
  \def\toclevel@Taskr{5}
\makeatother

\begin{document}
\section{Introduction}
\subsection{Problem definition}

\WP{Project management}
\Taskr{Project advisory board}
\end{document}

该\titleclass命令被定义为插入一个新级别之间现有级别（将较低级别向下推），而不是现有级别的替代。然而，手动创建替代级别（没有titlesec相关的编号行为）并不困难，您只需注意间距问题（注意：下面的示例无疑存在剩余问题）。

梅威瑟：

\documentclass{article}
\usepackage{amsmath}
%\usepackage{titlesec}

\newcounter{WP}
\newcounter{Taskr}
\newcommand{\WP}[1]{%
\stepcounter{WP}%
\setcounter{Taskr}{0}%
{\normalfont\normalsize\bfseries%
\bigbreak\noindent Work Package \theWP :\,#1}\par\noindent\ignorespaces%
}

\newcommand{\Taskr}[1]{%
\stepcounter{Taskr}%
{\normalfont\normalsize\itshape%
\par\noindent Task \theWP .\theTaskr :\,#1}\par\noindent\ignorespaces%
}

\begin{document}
\section{Introduction}
\subsection{Problem definition}

\WP{Project management}
This WP consists of two tasks.
\Taskr{Project advisory board}
Advise on the project.

\Taskr{Budget allocation}

\WP{Prototype}
\Taskr{Research existing solutions}

\subsection{Further considerations}

\end{document}

结果：
