没印象了， 只记得原来加过 JCheckBox render 和edit 是两个不同的东西，记住这点应该差不多了

如果你搜过的话，就当跳过这个
[解决办法]
你要继承下 AbstractCellEditor ;
public class ButtonCellEdit extends AbstractCellEditor implements
TableCellRenderer, TableCellEditor, ActionListener {
}
会有以下两个方法要你重写的，你加两个button进去， 一个做为 render,一个做为 button试试看
getTableCellRendererComponent(
getTableCellEditorComponent

不知道Button列在展现的时候是正常的，还是就是一个按钮。
看看我的博客，里面就有这样的例子，使用Table的CellRenderer和CellEditor实现。

PS：Renderer和Editor最好还是分开
