我试图在第一页上放置一个漂亮的页眉和页脚，但似乎无法弄清楚如何在所有页面上放置页脚。我试图找到分页符并插入命令\fancyhead{}，但除第一页外，所有页眉都消失了。但是，我想减少其余空白页中的页眉间距。有什么建议吗？谢谢。
我使用的代码如下：
\usepackage{fancyhdr}
\pagestyle{fancy}
\newcommand{\Header}[3]{
\fancyhf{} % Clear header/footer
\renewcommand{\headrulewidth}{0pt} % Remove header rule
\fancyhead[C]{%
\begin{tabular}{ @{} p{\textwidth} @{} }
\textbf{\textsf{#1}}\hfill \textbf{\textsf{#2}} \\
\hline
\centering \textsf{\small{#3}}
\end{tabular}}
\setlength{\headheight}{19pt}
\cfoot{\scriptsize \thepage}
\lfoot{\scriptsize \copyright 2019 Name}}
我的文件如下：
\documentclass[11pt, a4paper, twoside]{article}
\usepackage[a4paper,top=2.5cm,bottom=2cm,left=2.54cm,right=2.54cm,marginparwidth=1.75cm]{geometry}
\usepackage[utf8]{inputenc}
