我想在節、小節和子小節的編號後面放置一個點

Question

我的目標如問題標題所示。還有其他問題可以解決這個問題，但據我所知，所選的答案與我的其他現有程式碼不一致，總結如下。

\documentclass[11pt]{article}
\usepackage{amsmath,amsthm,titlesec}
\numberwithin{equation}{section}
\newcommand{\periodafter}[1]{#1.}
\newcommand{\presectionskip}{-1\baselineskip}
\newcommand{\postsectionskip}{0.3\baselineskip}

\makeatletter
    \renewcommand{\section}{\@startsection
        {section}{1}{0mm}%% name, level, indent
        {\presectionskip}% % beforeskip
        {\postsectionskip}% % afterskip
        {\normalfont\LARGE\bfseries}}% % style
    \renewcommand{\subsection}{\@startsection
        {subsection}{2}{0mm}
        {\presectionskip}
        {\postsectionskip}
        {\normalfont\Large\bfseries}}
    \renewcommand{\subsubsection}{\@startsection
        {subsubsection}{3}{0mm}
        {\presectionskip}
        {\postsectionskip}
        {\normalfont\normalsize\bfseries}}
\makeatother

%\usepackage[font=bf]{caption}
%\titleformat{\section}{}{\thesection.}{1ex}{\periodafter}
%\titleformat{\subsection}{}{\thesubsection.}{1ex}{\periodafter}
%\titlelabel{\thetitle.\quad}

\begin{document}
\section{Good section}\label{sec:refl}
\subsection{Superior subsection}\label{tableworks}
\subsubsection{This, the best of all subsections}
\end{document}

感謝您提供有關如何使其發揮作用的任何想法。
