TableCellRenderer & TableCellEditor 区别（转载）
TableCellRenderer就是用来绘制展示当前cell单元数值内容的，你可以用文字、数值或者图片来表示内容，当然最强大展示方式的就是通过自定义自己的renderer组件，通过Java2D来绘制各种天花乱坠的效果。
TableCellEditor主要是用来当用户点击在具体cell时进行编辑的组件，所以TableCellEditor除了具有TableCellRenderer一样的绘制功能外还可以进行交互动作，例如在cell上出现下拉框、勾选框甚至通过按钮弹出更复杂的对话框让用户进行输入编辑。
以下是在cell中嵌入start、stop两个按钮的表格，注意这里的renderer只是用来显示效果，并没有进行交互动作，真正进行动作的是当你将鼠标点击在cell上时，JTable定位上去的editor，所以不要徒劳在renderer上做点击事项处理，renderer是不会接受到交互事项的，renderer只是个画笔，你看到的start、stop按钮只是这个画笔画出来的内容，是虚的并没有真正的组件在上面。
