如何在两个时间戳之间存在的 java fx 8 表视图中显示数据

Question

我有一个问题，我找不到解决方案。

我正在尝试过滤我的 javafx8 tableview，但我遇到了问题。我不知道如何只显示两个时间戳之间存在的数据。

编辑：明确地说，我想知道如何使用文本字段为行配置开始和结束

PS：我的tableview截图：

我已经看过https://code.makery.ch/blog/javafx-8-tableview-sorting-filtering/。我在创建适当的 时遇到了麻烦Predicate，他们在 tuto 中向您展示了如何仅显示具有相同信息的信息。我想显示两者之间存在的信息。

PS：项目类型是时间戳
