精通JTable的高手请出手！

不好意思，我有2个问题要问。

1。 刷新JTable :代码如下:
this.myModel = new MyTableModel(column,rowData);
this.sorter = new TableSorter(myModel); //ADDED THIS
this.detailTable =new JTable(sorter);

当我更新了column,rowData后，我调用了
myModel = new MyTableModel(column,rowData);
detailTable.setModel(myModel);
执行后Table可以刷新，但是所有实现在sorter里的排序功能都不管用了。

2 。如何让JTable的第一列固定，滚动的时候永远在最左边？？？

有实现好的JTable代码最好了，先谢谢了。
