HTML <thead> Tag
To define a group of rows as the header of an HTML table, the HTML <thead> tag is used. It is used as a child of the <table> element along with the <tbody> and <tfoot> tags. The HTML <thead> tag, however, does not affect the layout of the table but is used for providing semantic information. One or more <tr> elements must be placed within a <thead> tag.
Syntax:
<thead> <tr></tr> <tr></tr> </thead>
Example:
<!DOCTYPE html>
<html>
<head>
<style>
thead {background-color:lightgray;}
tbody {background-color:pink;}
tfoot {background-color:wheat;}
table, th, td {
border: 2px solid brown;
}
</style>
</head>
<body>
<table>
<thead>
<tr>
<th>NAME</th>
<th>AGE</th>
</tr>
</thead>
<tbody>
<tr>
<td>Tom</td>
<td>20</td>
</tr>
<tr>
<td>Jerry</td>
<td>10</td>
</tr>
</tbody>
<tfoot>
<tr>
<td>Average</td>
<td>15</td>
</tr>
</tfoot>
</table>
</body>
</html>
