我有一个带复选框的表格。当我点击第三或第四列中的复选框时,我想要改变第一列中的复选框的选择。我希望能够更改同一行中的其他单元格。我已经有了这些列,所以我想知道单元格所在的行。同时,我也非常不确定我到目前为止是否正确。我目前的做法主要参考以下内容:
- http://download.oracle.com/javafx/2.0/ui_controls/list-view.htm - http://download.oracle.com/javafx/2.0/ui_controls/table-view.htm - http://download.oracle.com/javafx/2.0/api/index.html?javafx/scene/control/Cell.html

这里是我的SSCCE(简短自包含可编译示例)
如果以下代码有任何问题,请纠正我。
