How to add data in table in Vaadin

Question

Hi I am a newbie to Vaadin.

I am using Table property of vaadin to load the data from Domain Class but i have no idea how to set the table.additem for the data. I am using the following code to generate the column value

Table table = new Table("Customer Table");
  table.addContainerProperty("Street", String.class, null);
    for(DomainClass domainClass :  domainClassList) {
           //     table.addItem(domainClass.getStreet());
    }
layout.addComponent(table);

But it is showing the empty page.

A Vaadin best-practice is to work with Containers.

final Table table = new Table("Customer Table");
final BeanItemContainer<DomainClass> container = new BeanItemContainer<>(
            DomainClass.class, domainList);
table.setContainerDataSource(container);

If the DomainClass has a getter getStreet() then it's automatically mapped to a column with that name. Still you can set the table headers manually with table.setColumnHeader("street", "Street");

Maybe you find Vaadin's docs about Containers useful too.
