在HTML中如何创建表头？
使用HTML中的<thead>标记创建表头。HTML<thead>标记用于将标题添加到表中。thead标签与tbody标签和tfoot标签一起使用，以确定表的每个部分（页眉，页脚，正文）。
HTML<thead>标记还支持以下附加属性-
left
center
justify
char
middle
bottom
baseline
示例
您可以尝试运行以下代码以了解如何在HTML中实现<thead>标记-
<!DOCTYPE html>
<html>
<head>
<title>HTML thead Tag</title>
</head>
<body>
<table style = "width:100%" border = "1">
<thead>
<tr>
<td colspan = "4">This is the head of the table</td>
</tr>
</thead>
<tfoot>
<tr>
<td colspan = "4">This is the foot of the table</td>
</tr>
</tfoot>
<tbody>
<tr>
<td>Cell 1</td>
<td>Cell 2</td>
<td>Cell 3</td>
<td>Cell 4</td>
</tr>
<tr>
