使用宏来简化代码

Question

我的代码在 net 和 SO help 的帮助下运行。但现在我想使用宏来简化它。我不懂宏，但人们说它使代码更简化。

有人能指导我如何制作这个宏吗？如何使用它定义？

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{amsmath}
\usepackage{hyperref}
\usepackage[a4paper, total={6in, 8in}]{geometry}
\setlength\parindent{0pt}
\usepackage{xcolor}
\usepackage{setspace}
\begin{document}

\colorbox{black}{\makebox[\dimexpr\linewidth-2\fboxsep]{\color{white}\textbf {User schema}}}

\[
  \text{Users} \left\{ \begin{tabular}{@{}p{.8\linewidth}@{}}
    \textbf{ID}:  \textcolor{red}{ObjectId} -- Id do registro \\
    \textbf{Name}: \textcolor{red}{String} -- Name co usuario \\
    \textbf{date}: \textcolor{red}{Date} -- Date de Cadastro \\

    \end{tabular}

    \\

  \end{tabular}\right.\kern-\nulldelimiterspace

您可以在宏定义和新环境中隐藏重复的复杂代码。

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{amsmath}
\usepackage[a4paper, total={6in, 8in}]{geometry}

\usepackage{xcolor}
\usepackage{setspace}
\usepackage{hyperref}

\setlength\parindent{0pt}

\newenvironment{bracedtabular}
 {$\left\{\begin{tabular}}
 {\end{tabular}\right.\kern-\nulldelimiterspace$}
\newenvironment{lineditems}
 {\begin{tabular}[t]{@{}|l@{}}\\[-\normalbaselineskip]}
 {\end{tabular}\vspace{3pt}}
\newcommand{\group}[2][.]{\textcolor{#1}{\bfseries#2}}
\newcommand{\key}[1]{\textcolor{red}{#1}}
\newcommand{\longitem}[2][.9\linewidth]{\parbox[t]{#1}{\raggedright#2\unskip\strut}}
\newcommand{\header}[1]{%
  \colorbox{black}{%
    \makebox[\dimexpr\linewidth-2\fboxsep]{\color{white}\bfseries#1}%
  }%
}

\begin{document}

\begin{center}
\header{User schema}
