我試圖在第一頁上放置一個精美的頁首和頁腳，但似乎無法弄清楚如何將頁腳放置在所有頁面上。我試圖找到分頁符號並插入一個\fancyhead{}命令，除了第一頁之外，標題全部消失。但是，我想減少其餘空白頁面的頁眉間距。有什麼建議麼？謝謝，麻煩您了。
我正在使用的程式碼如下：
\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}
