java - JavaFX：如何根据列在搜索按钮单击时搜索 Tableview？

Question

我已将 csv 文件加载到 javafx 中的 tableview 中，并尝试根据帐号、地址、社区等在表中搜索属性。每个 Textfield 对应于特定的搜索目的以及下拉选择器。在我追求解决这个问题的过程中，我发现所有示例都积极过滤，因为我发现在按下搜索按钮时喜欢这样做。是否有适当的方法仅显示表中搜索的项目并在文本区域中显示信息？

表控制器：

public class FileGUI extends Application  {
    TableView table;
    ObservableList<PropertyData> data;


    @Override
    public void start(Stage primaryStage) {

        primaryStage.setTitle("Property Assesments");

        // For Label + table 
        // placed vertically (above one another)
        VBox vb1 = new VBox(20);    // set spacing between these nodes to 10

        // For Label + text field 
        // placed vertically (above one another)
        VBox vb2 = new VBox(20);     // set spacing between these nodes to 5

        // vb1 and vb2 will be placed horizontally 
        HBox hb = new HBox(150);     // set spacing between vb1 and vb2 to 20

        // set the scene
        Scene scene = new Scene(hb, 1000, 1000);


        //Set Text Labels
        Label label1 = new Label("Property Data");
        label1.setFont(new Font("Ariel",15));
        createSimpleTable();

        vb1.setAlignment(Pos.CENTER_LEFT);
        vb1.getChildren().addAll(label1,table);

        Label label2 = new Label("Find Property Assesment");
        label2.setFont(new Font("Ariel", 15));
        label2.setStyle("-fx-font-weight: bold;");


        Label label3 = new Label("Account Number:");
        label3.setFont(Font.font("Ariel", FontWeight.NORMAL, 12));
        label3.setPadding(new Insets(10, 0, 0, 0));

        TextField tf = new TextField();

        Label label4 = new Label("Address (#suite #house street):");
        label4.setFont(Font.font("Ariel", FontWeight.NORMAL, 12));

        TextField tf2 = new TextField();

        Label label5 = new Label("Neighbourhood:");
        label5.setFont(Font.font("Ariel", FontWeight.NORMAL, 12));

        TextField tf3 = new TextField();

        Label label6 = new Label("Assessment Class:");
        label6.setFont(Font.font("Ariel", FontWeight.NORMAL, 12));

        //Set dropdown menu selection
        MenuButton menuBtn = new MenuButton();
        menuBtn.setPadding(new Insets(0, 0, 0, 100));
        menuBtn.getItems().setAll(new MenuItem("Residential"), new MenuItem("Non Residential"), new MenuItem("Other Residential"));

        Button search = new Button("Search");
        Button reset = new Button("Reset");
        reset.setTranslateX(70);
        reset.setTranslateY(-37);

        TextArea box = new TextArea();
        box.setPadding(new Insets(0, 0, 0, 60));

        vb2.setAlignment(Pos.CENTER_LEFT);
        vb2.setSpacing(10);
        vb2.setPadding(new Insets(13, 0, 0, 6));
        vb2.getChildren().addAll(label2, label3, tf, label4, tf2, label5, tf3, label6, menuBtn, search, reset, box);

            @Override
            public void handle(ActionEvent event) {
                String accNumber = tf.getText();

            }
        };

        primaryStage.show();
