JQuery :: Using CSS To Change Position Of Table

I have this table on my html page:
<table id="t_menu_options" width="125" border="1" cellspacing="0" bordercolor="#F9F9F9">
<tr><td colspan="2"><font size="-2" face="Verdana"><strong>Options...</strong></font></td>
</tr><tr><td width="15%">></td>
<span id="edit"><td><font size="-2" face="Verdana"><span id="et">Edit</span></font></td></span>
</tr><tr><td width="15%">></td>
<span id="delete"><td><font size="-2" face="Verdana"><span id="dt">Delete</span></font></td></span>
</tr></table>

I start the page by hiding the above html by using
$('#t_menu_options').hide();
And that works.

Now upon some user mouseclick event, I want to show the html and move it to a position where the user clicked:
function showTaskOptionsMenu(e) {
alert(e.pageX+" "+e.pageY);
$('#t_menu_options').css({'left':e.pageX+'px','top':e.pageY+'px'}).show();
}
The alert command works as expected. however, the html is simply showed at the bottom of the page and is not moved to the desired location.
