我的表单（Jpanel）中有一个 jtable，它使用 jpa 通过 jtableBinding 绑定到 DB。（通过netbeans自动生成）
我通过在实体类@transient 中创建对应的字段，在jtable 中添加了一个复选框。这样我就不需要数据库表中此复选框的列。
我现在面临的问题是该复选框不可编辑。
我的实体类
@Entity
@Table(name = "PRODUCT")
@NamedQueries({@NamedQuery(name = "Product.findAll",
query = "SELECT p FROM Product p"),
@NamedQuery(name ="Product.findByProductId",

:purchaseCost"), @NamedQuery
