我认为没有做到这一点的干净方法，您将不得不修改生成的HTML。
我会将自定义行为附加到自动生成所需HTML的行上，如下所示：
new AjaxFallbackDefaultDataTable<MyCustomObject>( id, columns, dataProvider, rowsPerPage){ @Override protected Item<MyCustomObject> newRowItem(String id, int index, final IModel<MyCustomObject> model){ Item<MyCustomObject> item = super.newRowItem(id, index, model); item.add(new AbstractBehavior(){ private static final long serialVersionUID = 1L; @Override public void onRendered(Component component){ if(model.getObject().isEpicFail()){ component.getResponse().write( "<tr><td colspan="3">This is an epic fail</td></tr>"); } } }); return item; } private static final long serialVersionUID = 1L;}
