如果有人能教我如何在目录中的章节编号后面添加一个点，那就太好了。我使用 titletoc 包。
此外，我对缩进还有两个问题。我怎样才能在章节标题后的第一行获得缩进？我怎样才能（全局地）定义两个段落之间的空格（而不丢失缩进）？
\documentclass[a4paper,10pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[english]{babel}
\usepackage{titlesec}
\titleformat{\section}{\large\scshape}{\thesection.}{0.5em}{}
\usepackage{titletoc}
\titlecontents{section}[1.5em]{\large}{\contentslabel{1.5em}}{\hspace*{-1.5em}}{\titlerule*[1pc]{.}\contentspage}[\vspace*{0.3em}]
\begin{document}
\renewcommand\contentsname{\normalfont\large\textsc{Contents}}
\tableofcontents
\section{The first section}

就是这样：您必须使用 \contentslabel 的可选参数。请注意，您不需要重新定义 \contentsname。
\documentclass[a4paper,10pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[english]{babel}
\usepackage[indentafter]{titlesec}
\titleformat{\section}{\large\scshape}{\thesection.}{0.5em}{}
\usepackage{titletoc}
\titlecontents{section}[1.5em]{\large}{\contentslabel[\thecontentslabel.]{1.5em}}{\hspace*{-1.5em}}{\titlerule*[1pc]{.}\contentspage}[\vspace*{0.3em}]
\begin{document}
{\titleformat*{\section}{\centering\large\scshape}\tableofcontents}
\section{The first section}
