JavaFX：如何刷新表格？

Question

我在JavaFX TableView中刷新行样式有问题。

Java版本 “1.8.0_51”

的Java（TM）SE运行时环境（建立1.8.0_51-B16）

的HotSpot的Java（TM）服务器VM（25.51建设-B03，混合模式）

逻辑：

1. 加载数据到的tableView。
2. 通过setRowFactory将新样式设置为行。
3. 将新数据加载到表中。
4. 刷新新表格行的样式。 （不适用于我）

如何重新加载行的样式？

Answer 1

尝试tableView.refresh()。它自Java 8u60起可用于JavaFX。

Answer 2

这里是一个小把戏我发现在​​一年前...

myTableView.getColumns().get(0).setVisible(false); 
myTableView.getColumns().get(0).setVisible(true); 

这可能不是最好的方式，但它适合我...
