JavaFX我的主菜单上有2个类似的TableView，如果我先搜索它，实际上并不会删除某些内容

如何解决JavaFX我的主菜单上有2个类似的TableView，如果我先搜索它，实际上并不会删除某些内容

嘿，我先感谢您提供任何帮助，我有一个主菜单，您可以在其中搜索，添加，删除和修改两个不同的TableView。充满ObservableList的代码可以完美地工作，但是具有ObservableList的代码却不能正常工作，即使我复制并粘贴了代码并相应地将Part for Product切换了出去。如果使用“产品”，则如果我提前搜索它，实际上并不会删除该行。只会将其从搜索列表中删除（如果我返回完整列表，则会显示备份。）

这是我的主菜单控制器：

这是我的清单类和方法：

这是我的主要建议，如果您出于某些原因需要它：

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
import model.InHouse;
import model.Inventory;
import model.Outsourced;
import model.Product;

/**

public class InventorySystem extends Application{

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        // Todo code application logic here
        
        InHouse inhouse1 = new InHouse(1,"Bucket",5.99,5,2,200,8451);
        InHouse inhouse2 = new InHouse(3,"Wrench",17.99,10,40,3201);
        
        Outsourced outsource1 = new Outsourced(2,"Hammer",8.99,11,7,70,"Wisconsin Tools");
        Outsourced outsource2 = new Outsourced(4,"Shovel",20.99,18,4,78,"Hardware Co");
        
        Product product1 = new Product(1,200);
        Product product2 = new Product(2,70);
        Product product3 = new Product(3,40);
        Product product4 = new Product(4,78);
        
        Inventory.addPart(inhouse1);
        Inventory.addPart(outsource1);
        Inventory.addPart(inhouse2);
        Inventory.addPart(outsource2);
        
        Inventory.addProduct(product1);
        Inventory.addProduct(product2);
        Inventory.addProduct(product3);
        Inventory.addProduct(product4);
        
        launch(args);
    }

    @Override
    public void start(Stage stage) throws Exception {
        Parent root = FXMLLoader.load(getClass().getResource("/view/MainMenu.fxml"));
        Scene scene = new Scene(root);
        stage.setScene(scene);
        stage.setTitle("Inventory System");
        stage.show();
    }
