int editingRow = table.getSelectedRow();

        if(editingRow!=-1){

            TableCellEditor cellEditor = table.getCellEditor(editingRow,column_index);

            cellEditor.stopCellEditing();

        }

------解决方案--------------------

假设jtable是你的表格对象。
在取值直前加下面的代码：
Java code


TableCellEditor cellEditor = jtable.getCellEditor();
if(cellEditor != null ){
    cellEditor.stopCellEditing();
}
