jtable编辑之后,一点别的地方,刚刚编辑的就没了,没发保存,试过好多方法都不行阿.方法1:table.setColumnSelectionAllowed(false);
if (table.isEditing())
{table.getCellEditor(table.getEditingRow(), table.getEditingColumn()).stopCellEditing();}
试了试没有效果，不知道写在哪里起作用？？方法2: 我是加在 自己建的 类 ResultSetTableModel1,继承的(AbstractTableModel)里的
private boolean stopCellEditing(CellEditor cellEditor){
if(cellEditor!=null){
return cellEditor.stopCellEditing();
}
return true;
}
这个方法也不行,
谁能告诉改怎么办? 用事件监听呢?
