может, как-то так?

<script type="text/javascript" src="jquery-1.3.2.js"></script>
<script type='text/javascript'>
$(document).ready(function()
{
$('#add_war_href').click(function() {$('#new_war').append($("<tr><td>1111</tr></td>"))});
});
</script>
<button id="add_war_href">add</button>

<table>
    <tbody id="new_war">
    </tbody>
</table>
