我对 LaTEX 还不熟悉。我正在编写一个大型文档，其中需要对每个条款进行编号，因此我使用 LaTEX 中的枚举功能，效果很好。有时我需要在 2 个或更多级别中编写条款。因此我使用嵌套的“枚举”解决方案。但是当我转到级别 II 时，特定条款的第一行中有一个小的额外空间。但是，条款的其余行完全符合要求。在枚举级别 I 中编写文本时不会出现此问题。我如何编辑以便枚举级别 II 或更高级别也显示与级别 I 中一样完全对齐的文本？
请帮忙！！！
最小代码示例如下：

\usepackage[square, numbers, comma, sort&compress]{natbib}
\usepackage{verbatim}
\usepackage{lipsum}
\usepackage{textcomp}
\usepackage{vector}
\usepackage{url}
\usepackage{natbib}
\usepackage[compact]{titlesec}
\titleformat{\chapter}[display]
{\normalfont\huge\bfseries}{\chaptertitlename\ \thechapter}{01pt}{\Huge}
\titlespacing*{\chapter}{0pt}{01pt}{01pt}
\setlength{\parskip}{6pt}
\usepackage{fancyhdr}
\usepackage[document]{ragged2e}
\usepackage{enumitem}
\usepackage{etoolbox}
\usepackage{array}
\titleformat{\chapter}[display]{\normalfont\bfseries}{}{0pt}{\huge}
\titleformat{\section}{\normalfont\upshape\bfseries}{\thesection}{2.7em}{\large}
\titleformat{\subsection}{\normalfont\upshape}{\thesubsection}{2.5em}{\normalsize}
\titleformat{\paragraph}{\normalfont\upshape}{\thesubsection}{1em}{\normalsize}
\setcounter{secnumdepth}{4}
\begin{document}
\mainmatter
\pagestyle{fancy}
\renewcommand{\chaptermark}[1]{ \markboth{#1}{} }
\renewcommand{\sectionmark}[1]{ \markright{#1}{} }
\renewcommand{\headrulewidth}{0.4pt}
\renewcommand{\footrulewidth}{0.4pt}%
\addtocontents{toc}{\vspace{2em}}
\justifying
\pretolerance=10000
\begin{enumerate}[leftmargin=4.5em,labelsep=2.7em,align=right,label={\thesection.\arabic*}]
\item \lipsum
\vspace{0.5em}
\begin{itemize}
\item \lipsum
\end{itemize}
\end{enumerate}
\end{document}

此解决方案在开始枚举之前存储默认值。或者，您可以使用，[labelwidth=*, labelsep=*]但结果不太一样。
