JavaFX表未显示数据

下面我将编写一个JavaFX代码来填充和显示表中的记录。记录可以是多个，并且记录是LibraryMember类（如下所示）的对象，但该表不显示记录。请找出我的代码中有什么错误

private TableView<LibraryMember> table;
public ObservableList<LibraryMember> allMemberDataRecords = list;

/*
The data in the above list is in the following format:
[Member Info: ID: 1004, name: Ricardo Montalbahn, 641-472-2871 (501 Central, Mountain View, 94707), Member Info: ID: 1003, name: Sarah Eagleton, 451-234-8811 (42 Dogwood Dr., Fairfield, 52556), Member Info: ID: 1002, name: Drew Stevens, 702-998-2414 (1435 Channing Ave, Palo Alto, 94301), Member Info: ID: 1001, name: Andy Rogers, 641-223-2211 (5001 Venice Dr., Los Angeles, 93736)]
*/


table = new TableView();
table.setEditable(true);

TableColumn idCol = new TableColumn("Member Id");
idCol.setCellValueFactory(new PropertyValueFactory<LibraryMember, String>("memberId"));

TableColumn firstNameCol = new TableColumn("First Name");
firstNameCol.setCellValueFactory(new PropertyValueFactory<LibraryMember, String>("firstName"));

TableColumn lastNameCol = new TableColumn("Last Name");
lastNameCol.setCellValueFactory(new PropertyValueFactory<LibraryMember, String>("lastName"));

TableColumn streetCol = new TableColumn("Street");
lastNameCol.setCellValueFactory(new PropertyValueFactory<LibraryMember, String>("lastName"));

TableColumn cityCol = new TableColumn("City");
cityCol.setCellValueFactory(new PropertyValueFactory<LibraryMember, String>("city"));

TableColumn stateCol = new TableColumn("State");
stateCol.setCellValueFactory(new PropertyValueFactory<LibraryMember, String>("state"));

TableColumn zipCol = new TableColumn("Zip");
zipCol.setCellValueFactory(new PropertyValueFactory<LibraryMember, String>("zip"));

TableColumn phoneCol = new TableColumn("Telephone");
phoneCol.setCellValueFactory(new PropertyValueFactory<LibraryMember, String>("telephone"));

table.setItems(allMemberDataRecords);
table.getColumns().addAll(idCol, firstNameCol, lastNameCol, streetCol, cityCol, stateCol, zipCol, phoneCol);

final VBox vbox = new VBox();
vbox.setSpacing(5);
vbox.getChildren().add(table);
grid.add(vbox, 0, 1);

Scene scene = new Scene(grid);
scene.getStylesheets().add(getClass().getResource("library.css").toExternalForm());
setScene(scene);

请创建一个。将重现问题所需的一切都放在

start

方法中，并发布完整的项目类型将是一个好主意；如果您已经确认这不是问题所在，请确保填充数据的逻辑也在那里，并且没有它可能得到的那么简单（=一些硬编码值）。现在我发现有几种方法可能会出错，我们无法判断哪种方法适用…@Agha Salman我不知道你为什么要这样做？-><代码>公共可观察列表allMemberDataRecords=列表这是您在真实代码中拥有的吗？名单是从哪里来的？请确保

列表

中有数据要填充到表中。
