添加新行后如何自动对JTable排序？

Question

在向JTable添加新行时如何在JTable中对行进行升序或降序排序？

Answer 1

Depending on your needs whether or not you need to sort on multiple columns, you can add a TableModelListener to your table model, to execute custom behaviour when the table model changes. Just implement the

public void tableChanged(TableModelEvent e)

method to capture the event and sort the required collumn. One way of doing this is to map work with an index map which refers to the data of the column you want to sort and resort the index map according to the column that you want to sort.
