从JTable单元获取值

Question

I made a column editable in Jtable.

I want old values from a cell when I have finished editing a cell

Answer 1

You can get the value by using

table.getModel().getValueAt(row_index, col_index);

where table is the name of the table and it will return an Object

Go through this Getting cell value . It may be useful for you.

Answer 2

You can use a TableCellListener , like they show here . It uses a PropertyChangeEvent to keep track of the old and new values.

Answer 3

您还可以创建自己的TableModel实现，并覆盖setValueAt方法以跟踪更改。

Answer 4

Add a TableModelListener to your TableModel. Whenever an event fires you can updated the contents of your text field with the new value in the cell.
