How do you append rows to a table using jQuery?

Hi I was trying to add a row to a table using jQuery, but it is not working.
What might be the reason?

And, can I put in some value to the newly added row..?

Here is the code:

<html>
<head>
    <script type="text/javascript" src="jquery.js"></script>
    <script type="text/javascript">
        $('a').click(function() {
            $('#myTable').childs('tr').append('<tr class="child"><td>blahblah</td></tr>');
        });
    </script>
    <title></title>
</head>
<body>
    <a href="">Link</a>
    <table id="myTable">
        <tbody>
            <tr>
                <td>
                    test
                </td>
            </tr>
        </tbody>
    </table>
</body>
</html>

I'm assuming you want to add this row to the <tbody> element, and simply using append() on the <table> will insert the <tr> outside the <tbody> , with perhaps undesirable results.

$('a').click(function() {
   $('#myTable tbody').append('<tr class="child"><td>blahblah</td></tr>');
});

EDIT: Here is the complete source code, and it does indeed work: (Note the $(document).ready(function(){}); , which was not present before.

<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
    $('a').click(function() {
       $('#myTable tbody').append('<tr class="child"><td>blahblah</td></tr>');
    });
});
</script>
<title></title>
</head>
<body>
<a href="javascript:void(0);">Link</a>
<table id="myTable">
  <tbody>
    <tr>
      <td>test</td>
    </tr>
  </tbody>
</table>
</body>
</html>

The following code works

<html>
<head>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
function AddRow()
{
    $('#myTable').append('<tr><td>test 2</td></tr>')
}
</script>
<title></title>
</head>
<body>
<input type="button" id="btnAdd" onclick="AddRow()"/>
<a href="">test</a>
<table id="myTable">
  <tbody >
    <tr>
      <td>
        test
      </td>
    </tr>
  </tbody>
</table>
</body>
</html>

Note this will work as of jQuery 1.4 even if the table includes a <tbody> element:

jQuery since version 1.4(?) automatically detects if the element you are trying to insert (using any of the append(), prepend(), before(), or after() methods) is a <tr> and inserts it into the first <tbody> in your table or wraps it into a new <tbody> if one doesn't exist.

Maybe this is the answer you are looking for. It finds the last instance of <tr /> and appends the new row after it:

<script type="text/javascript">
    $('a').click(function() {
        $('#myTable tr:last').after('<tr class="child"><td>blahblah</td></tr>');
    });
</script>
