仅更新<col>中的值

Question

So I really need to know if it's possible to update the values under a specific column on a table.

<table>
    <col with="auto">
    <col with="auto">
    <col with="auto" id="update_me">

<?php
for(hundreds of lines){
?>
    <tr>
    <td>something 0</td>
    <td>something 1</td>
    <td>Need to update</td>
    <tr>
<?php
}
?>

I will be using:

<script>
$(document).ready(function() {
$("#update_me").load("response.php");
var refreshId = setInterval(function() {
$("#update_me").load('response.php');
}, 6000);
$.ajaxSetup({ cache: false });
});
</script>

The php will only generate the values from the specific column!

<script>
   $(document).ready(function() {
      var refreshId = setInterval(function() {
         $.getJSON('response.php', function(data) {
            $.each(data, function(index, value) {
               $('#value'+index).html(value).show();
        });
      });       
      }, 3000);
      $.ajaxSetup({ cache: false});
   });
</script>
