具有复杂TableColumn的JavaFX TableView

Question

与此处的问题类似：Javafx tableview with data from multiple classes 我正在尝试创建一个由多个类组成的表。后端是sqlite表，我正在尝试实现这里找到的Toxi解决方案：http://tagging.pui.ch/post/37027745720/tags-database-schemas这就是为什么我的简化示例就是这样 - 分成不必要的类。

这是我试图弄清楚的Tag列。一个包装类是最简洁的方法，一个BookmarkTag类？您可以设置事件处理程序以在更新行时填写此其他列吗？最终，单元格将包含更好的标签显示（可点击图标）。

谢谢。
