    As bellow we can remove table rows with specific row id

    <html>
    <head>
        <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.js" type="text/javascript"></script>
    <script type="text/javascript">
    function remove(id)
    {
    $('table#test tr#'+id).remove();
    // or you can use bellow line also
    //$('#test tr#'+id).remove();
    }
    </script>
        </head>
    <body>
    <table id="test">
     <tr id="1"><td>bla</td><td><input type="button" onclick="remove(1)"value="Remove"></td></tr>
     <tr id="2"><td>bla</td><td><input type="button" onclick="remove(2)" value="Remove"></td></tr>
     <tr id="3"><td>bla</td><td><input type="button" onclick="remove(3)" value="Remove"></td></tr>
     <tr id="4"><td>bla</td><td><input type="button" onclick="remove(4)" value="Remove"></td></tr>
    </table>
    </body></html>

    ID attributes cannot start with a number and they should be unique. In any case, you can use :eq() to select a specific row using a 0-based integer:

    // Remove the third row
    $("#test tr:eq(2)").remove();
    

    Alternatively, rewrite your HTML so that it's valid:

    <table id="test">
     <tr id=test1><td>bla</td></tr>
     <tr id=test2><td>bla</td></tr>
     <tr id=test3><td>bla</td></tr>
     <tr id=test4><td>bla</td></tr>
    </table>
    

    And remove it referencing just the id:

    $("#test3").remove();

    Simply $("#3").remove(); would be enough. But 3 isn't a good id (I think it's even illegal, as it starts with a digit).

    $('#3').remove();
    

    Might not work with numeric id's though.

    Use the :eq selector:

    $("#test tr:eq(2)").remove();
