您实现
setValueAt()您
AbstractTableModel不能开火，将通知该改变侦听器的事件：
@Overridepublic void setValueAt(Object value, int row, int column) { rowData[row][column] = value; fireTableCellUpdated(row, column);}纠正后，a
TableModelListener将看到每个更改。尝试注释掉该
fireTableCellUpdated()行以查看区别。
此外：
只能 在事件分配线程上构造和操作Swing GUI对象。
避免
set(Preferred|Maximum|Minimum)Size
在Java Swing中使用方法；setPreferredScrollableViewportSize()
危险性稍差一些。
