<hyperlink rel=”stylesheet” href=””>
<script src=””> </script>
<script src=””> </script>
<li> Home </li>

<!DOCTYPE html> <html> <mind> <title> Table Data </name> <meta charset=”utf-8″> <meta name=”viewpoint” content material=”width=device-width”, initial-scale=”1″> <hyperlink rel=”stylesheet” href=””> <script src=””> </script> <script src=””> </script> </mind> <body> <nav> <ul> <li> Home </li> </ul> </nav> </body> </html>
