我正在使用 titlesec 删除章节和文本之间的空格，\titlespacing{\section}{0pt}{0em}{0pt}{}但这在段落结尾和章节之间不起作用，负值会被忽略\titlespacing{\section}{0pt}{-1em}{0pt}{}。
\documentclass[12pt, a4paper]{extreport}
\usepackage[margin=2cm, top=2cm, right=1.4cm, bottom=2cm, left=2.8cm]{geometry}
\setlength{\parskip}{0em}
\usepackage{setspace}
\linespread{1.5}
\usepackage{titlesec}
\titlespacing{\chapter}{0pt}{-32pt}{0pt}{}
\titlespacing{\section}{0pt}{0em}{0pt}{}
\titlespacing{\subsection}{0pt}{0pt}{0pt}{}
\titlespacing{\subsubsection}{0pt}{0pt}{0pt}{}
\titleformat{\chapter}[hang]
{\normalsize\bfseries\center}
{\thechapter.}
{0.5em}

\titleformat{\section}[hang]

我怎样才能删除段落末尾和章节之间的这个空格？
对不起，我的英语不好。

使用.\centering代替\center.center是一个列表命令并引入间距。
