中的代码> RowSorterListener 是指定正确返回索引（来自 RowSorterListener s event）

• code in RowSorterListener is designatet to returns the index correctly (from RowSorterListeners event)

  默认情况下，你永远不需要知道 JTable的订购 s视图，所有这些事件都是模型事件，

  by default you never need to know ordering from JTables view, all those events are models events,

  add TableColumnModelListener 如果要跟踪 columnMoved ，则以编码方式排序的所有事件都将绘制在中JTable 正确查看

  add TableColumnModelListener in the case that you want to trace columnMoved, all events from sorting programatically are painted in JTables view correctly

  1st。没有列重新排序的attemtp，

  1st. attemtp without column reordering,

  Column NO. - 0 is sorted
  Column NO. - 1 is sorted
  Column NO. - 2 is sorted
  Column NO. - 3 is sorted
  Column NO. - 4 is sorted
  
  ... and so on

  • 第二名。尝试列重新排序（通过鼠标拖动）

  • 第三。如果没有初始化Swing Timer并且所有事件都是由用户手提出的，那么尝试相同的正确输出

    • 3rd. attempt the same correct output if Swing Timer isn't initialized and all event are made by users hand

      例如

      。
