如何在Vaadin 7.7.6中使表格列可编辑

Question

我在Vaadin中有一个表，其中有4个生成的列。我希望其中之一是可编辑的。因此，该表具有以下列：

private LazyBeanTable<EmailTemplateMapping> createEmailTemplateConfigurationTable()
{
    final LazyBeanTable<EmailTemplateMapping> table = new LazyBeanTable<>();
    table.setSelectable(true);
    table.setMultiSelect(true);
    table.setSizeFull();
    table.addGeneratedColumn(I18N.TEMPLATE_NAME.msg(), (source, itemId, columnId) -> itemId.getTemplateName() );
    table.addGeneratedColumn(I18N.TEMPLATE_DESCRIPTION.msg(), (source, itemId, columnId) -> itemId.getTemplateDescription());
    table.addGeneratedColumn(I18N.LANGUAGE.msg(), (source, itemId, columnId) -> itemId.getTemplateLanguage());
    table.addGeneratedColumn(I18N.SYSTEMCONFIG_TAB_EMAIL_DOMAIN_MAPPINGS_ACTIVE.msg(), (source, itemId, columnId) -> formatActive(itemId.isActive()));
    return table;
}

并且有一个懒豆表的构造函数，

private final Table table;
private final LazyBeanItemContainer<BEANTYPE> container;

public LazyBeanTable()
{
    container = new LazyBeanItemContainer<>((pageable, specification) -> getHandler() == null ? null : getHandler().getItems(pageable, specification), specifications, this::onSizeChanged);
    table = new Table();
    table.setContainerDataSource(container);
    table.addValueChangeListener(event -> fireValueChangeEvent());
    table.addItemClickListener(event -> fireItemClickedEvent(container.getBean(event.getItemId()), event.isDoubleClick()));
    setCompositionRoot(table);
}

我需要描述栏可编辑。

table.addGeneratedColumn(I18N.TEMPLATE_DESCRIPTION.msg(), (source, itemId, columnId) -> itemId.getTemplateDescription());

我该怎么做。请帮助
