html - How can I simply freeze the first row of my table using pure Javascript, no plugins? -


i need table work in latest version of google chrome (so no need worry cross-browser solutions, older versions of ie, etc.)

i looking solution freeze first row , not having success. if exclude word relative in css position: fixed relative; header rows stack on top of each other. not sure how header stay @ top of screen when scroll.

code table

<html> <head>  <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.js"></script> <script type="text/javascript">  $(document).ready(function(){     $( "#status_report .measure[data-bg='1']").css('background', 'red');     $( "#status_report .measure[data-bg='2']").css('background', 'grey');     $( "#status_report .measure[data-bg='3']").css('background', 'yellow');     $( "#status_report .measure[data-bg='4']").css('background', 'green'); });  </script> <style type="text/css"> th{     position: fixed relative;     background:#111;     color:#fff;     padding: 2px; } td {     background:#ddd;     max-width: 200px;     overflow: hidden;     text-overflow: ellipsis;     white-space: nowrap;     padding: 2px; } </style> </head> <body> <table id="status_report"> <tr>     <th>field1</th>     <th>field2</th>     <th>field3</th> </tr> <tr> <?php foreach( $data $row ) : ?> <tr>     <td><?php echo $row['field1']; ?></td>     <td class = "measure" data-bg="<?php echo $row['field2']; ?>"><?php echo $row['field2']; ?></td>         <td class = "measure" data-bg="<?php echo $row['field3']; ?>"><?php echo $row['field3']; ?></td>         </tr> <? endforeach; $dbh = null; ?> </table> </body> </html>

position: fixed relative invalid css. when set fixed, position "resets", in, object not stay "where it's suppose be" , became relative document, need set it's position using top, left etc.

that's why stack.
