问如何基于行项设置Vaadin Grid Pro的editComponent中的不同选择项

EN

    // Use custom editor
    EmailField emailField = new EmailField();
    emailField.setWidth("100%");
    emailField.addThemeName("grid-pro-editor");
    grid.addEditColumn(Person::getEmail)
            .custom(emailField, (item, newValue) -> {
                item.setEmail(newValue);
            }).setHeader("E-mail ");
    // Use edit started listener to set the field conditionally enabled
    grid.addCellEditStartedListener(event -> {
        if (!event.getItem().isSubscriber()) {
            emailField.setReadOnly(true);
        } else {
            emailField.setReadOnly(false);
        }
    });
