rowspan 처리하기

function rowspan(className){
    var txt;
    var rows;
    $("." + className).each(function() {
        txt = $(this).text();
        if(txt.length === 0)
            return true;

        rows = $("." + className + ":contains('" + txt + "')");

        if (rows.length > 1) {
            rows.eq(0).attr("rowspan", rows.length);
            rows.not(":eq(0)").remove();
        }
    });
}

rowspan("rowspan");

rowspan 을 원하는 td에 class 추가 호출하면 됨.
