这里如何是一个分页控制集成的TableView一些示例代码。
代码来自Shakir Quasaroff对Oracle的JavaFX论坛对PaginatedTableView控件的请求的回答。示例代码是纯Java解决方案,而不是原始问题中的Java代码/ FXML混合代码。

此外,第三方LGPL许可TiwulFX library by Panemu提供的TableView(包括分页)高级功能。
这写成控制器类? – user2158598 2013-03-11 23:30:38
不,这个答案中的解决方案不是基于fxml的,它与控制器类无关。 – jewelsea 2013-03-12 00:43:27
我认为提供的示例包含大量不必要的代码,并且做了不必要的工作。为什么为每个页面重新创建tableView?为什么在for循环中创建?看到我的答案为清理版本。没有冒犯的意思。 – 2014-08-21 10:41:52
