Use the headers attribute in HTML to add one or more header cells a cell is related to in HTML.
Example
You can try to run the following code to implement the headers attribute −
<!DOCTYPE html>
<html>
<head>
<style>
table, th, td {
border: 2px solid blue;
}
</style>
</head>
<body>
<table style = "width:100%">
<tr>
<th id = "name">Subject ID</th>
<th id = "email">Subject Name</th>
</tr>
<tr>
<td headers = "name">001</td>
<td headers = "email">Mathematics</td>
</tr>
</table>
</body>
</html>
