<p> <span>要使用此界面，创建新编辑器的开发人员可以使新组件实现该接口。</span> <span>或者开发人员可以选择的包装为基础的方法，并提供一个实现了一个同伴对象<code>CellEditor</code>接口（见<code>JCellEditor</code>为例）。</span> <span>如果用户希望使用第三方ISV编辑器的包装方法是非常有用<code>JTable</code> ，但ISV没有实现<code>CellEditor</code>接口。</span> <span>用户可以简单地创建一个包含第三方编辑器对象实例的对象，并将<code>CellEditor</code> API“转换”为第三方编辑器的API。</span> </p>
