从this code.makery博客，我能够理解tableview排序和过滤的工作原理和实现方式。问题是博客显示了一个不使用ListProperty的示例。当我尝试使用ListProperty更改代码示例时，不会进行排序和过滤。
这是博客提供的内容
FilteredList<Person> filteredData = new FilteredList<>(masterData, p -> true);
filterField.textProperty().addListener((observable, oldValue, newValue) -> {
filteredData.setPredicate(person -> {
if (newValue == null || newValue.isEmpty()) {
return true;
}
String lowerCaseFilter = newValue.toLowerCase();
if (person.getFirstName().toLowerCase().contains(lowerCaseFilter)) {
return true;
} else if (person.getLastName().toLowerCase().contains(lowerCaseFilter)) {
return true;
}
return false;
});
});
SortedList<Person> sortedData = new SortedList<>(filteredData);sortedData.comparatorProperty().bind(personTable.comparatorProperty());
personTable.setItems(sortedData);
