页面排序的问题

//排序码
function resetSort(obj){
    var container = $(obj).closest("div");//找到第一个匹配的层
    var tables = $(">table", container);//找层的子项table标记
    var tableCount = tables.size();//统计table标记的个数
    var temp = $("<div></div>");//定义临时存放数据的标记
    $("select[name='sort']").change(function () {
        var self = $(this);
        var table = self.closest("table");        var newIdx = parseInt(self.val());
//alert(newIdx);        if (newIdx == 1) {
            table.prependTo(container);
        } else if (newIdx == tableCount){
            table.appendTo(container);
        } else {
            table.appendTo(temp);
//alert(newIdx - 2);
            $(">table:eq("+(newIdx - 2)+")", container).after(table);
        }        $(">table select[name='sort']", container).each(function (i, n) {
            $(this).val(i + 1);
        });
    });

            </table>
        </div>我想实现的功能就是改变select，顺序就发生变化，排序的那段代码还有点问题，请大家帮我修正一下，
因为if (newIdx == 1) {
            table.prependTo(container);
        }
有点问题，我的div里面有个table[0]是必须放在第一位的，所以在选择为1的时候，也必须要放在这个表格后面，请大家帮我修改一下
