                    {
                        if ($('td').hasClass("csstdgreen") && $('td').attr('rowspan'))
                        {
                            alert("Hi");
                            $('.csstdgreen').removeClass('csstdselected');
                            $('td').removeClass('csstdgreen').addClass('csstdselected');
                        }

Use the reference this to make changes to the targeted td:

$('#myTable td').click(function () {
    if ($(this).hasClass("csstdgreen") && $(this).attr('rowspan') )
    {
        alert("Hi");
        $('.csstdgreen').removeClass('csstdselected');
        $(this).removeClass('csstdgreen').addClass('csstdselected');
    }
});​
