Answer 1

建议楼主看下  swingHack， 那里面有专门一节讲了关于JTable的排序

Answer 2

JDK1.6?
自带了，点击列头排序

     有人说在这里面定义个数组  在用冒泡排序  不知道这么弄啊。有那位高手知道吗？谢谢 ！！！

Answer 4

恩 现在的方法自己写好了嘿嘿  
  public void paixv(String name, String type) {
        Object[] b = new Object[rows.size()];
        for (int i = 0; i < b.length; i++) {
            b[i] = (Vector) rows.get(i);
        }
        for (int i = 0; i < b.length; i++) {
            for (int u = 0; u < (b.length - 1) - i; u++) {
                Vector v1 = (Vector) b[u];
                Vector v2 = (Vector) b[u + 1];
                int num1 = 0;
                int num2 = 0;
                if (name.equals("Stu_id")) {
                    num1 = Integer.parseInt((String) v1.get(0));
                    num2 = Integer.parseInt((String) v2.get(0));
                } else {
                    num1 = Integer.parseInt((String) v1.get(2));
                    num2 = Integer.parseInt((String) v2.get(2));
                }                if (type.equals("shenngxv")) {
                    if (num1 > num2) {
                        Object o1 = b[u];
                        b[u] = b[u + 1];
                        b[u + 1] = o1;
                    }
                } else {
                    if (num1 < num2) {
                        Object o1 = b[u];
                        b[u] = b[u + 1];
                        b[u + 1] = o1;
                    }
                }            }
        }        rows.removeAll(rows);
        for (int i = 0; i < b.length; i++) {
            rows.add(b[i]);
            jTable1.setRowHeight(jTable1.getRowHeight());
        }
    }
    总算做出来了嘿嘿   结贴了啊 !!!!
