\titlesec 和 Chapter§ion 缺失零錯誤

\titlesec 和 Chapter§ion 缺失零錯誤

我在這裡看了又看，尋找可能的答案，但我還不夠。我甚至參考了 titlesec .pdf 說明，但仍然沒有任何線索。我的\chapter主體有問題，說它缺少一個零。

Chapter 1.
! Missing number, treated as zero.
<to be read again> 
                   \relax 
l.39 \chapter{Spanning Tree Protocol Concepts}

我的第一章有錯誤。

我正在輸入我的筆記，對於每一章，我想顯示“第 1 章”，然後“這是該章的標題” \section*。有什麼想法嗎？

答案1

該命令\titlespacing需要三個長度。

所以它們應該是這樣的

\titlespacing{\chapter}{0pt}{0pt}{4pt}

和

\titlespacing{\section}{0pt}{5pt}{5pt}

你也有/end{document}而不是\end{document}

我不知道你想要實現什麼，但這是你修改後的 MWE：

請注意，您還缺少一個長度

\titleformat{\section}
    {\normalfont\Large\bfseries}
    {\thesection}{}{}

應該是這樣的

\titleformat{\section}
    {\normalfont\Large\bfseries}
    {\thesection}{1em}{}

您只是沒有註意到這一點，因為在 MWE 中您只有未編號的部分。

答案2

我建議一個小的改進：以連字符開頭的行具有逐項結構，因此我過去使用 es進行enumitem格式化。的第四個參數缺少長度：itemizeendash\titleformat{\section}{…}

\usepackage{enumitem}
\usepackage{bookmark}
\usepackage{booktabs}
\usepackage{titlesec}
\usepackage{parskip}
%\usepackage{indentfirst} used to indent first paragraph

\setlist[itemize, 1]{label = \textendash}

%%%CHAPTER FORMAT/SPACING
\titleformat{\chapter}[display] %cmd and shape
    {\normalfont\LARGE\bfseries} %textformat \typeoffont\size\ifits bold?

    {1pt} %seperation from num to title name
    {} %before code (blank means default)
\titlespacing{\chapter}{0pt}{0pt}{4pt} %cmd left margin befoe titel and after title
%%%SECTION FORMAT/SPACING
\titleformat{\section}
    {\normalfont\Large\bfseries}
    {\thesection}{0.5em}{}
\titlespacing{\section}{0pt}{5pt}{5pt}

\setlist{nosep}
\setlength{\intextsep}{1pt}
\setlength{\parskip}{0pt}
