Java “添加”和“删除”仅影响表而不影响列表我应该如何使其影响列表
因此，我在DocTableController中添加和删除函数，以在GUI中编辑表。我将ArrayList从主控制器链接到DocTableController。 当我删除并添加该项时，它似乎仅对表有效，而对列表无效。一旦我返回主菜单并再次返回可修改场景，列表将重新初始化。当我再次进入tableView时，不会改变 主控制器Java “添加”和“删除”仅影响表而不影响列表我应该如何使其影响列表,java,javafx,arraylist,tableview,scenebuilder,Java,Javafx,Arraylist,Tableview,Scenebuilder,因此，我在DocTableController中添加和删除函数，以在GUI中编辑表。我将ArrayList从主控制器链接到DocTableController。 当我删除并添加该项时，它似乎仅对表有效，而对列表无效。一旦我返回主菜单并再次返回可修改场景，列表将重新初始化。当我再次进入tableView时，不会改变 主控制器 public class FXMLdocumentController implements Initializable { @FXML Label date;
