Grid.setColumns介绍

[英]Sets the columns and their order based on their column ids. Columns currently in this grid that are not present in the list of column ids are removed. This includes any column that has no id. Similarly, any new column in columns will be added to this grid. New columns can only be added for a Grid created using Grid#Grid(Class) or #withPropertySet(PropertySet).
[中]根据列ID设置列及其顺序。此网格中当前不在列ID列表中的列将被删除。这包括任何没有id的列。类似地，列中的任何新列都将添加到此网格。只能为使用网格#网格（类）或#withPropertySet（PropertySet）创建的Grid添加新列。

  }

public class MyUi extends UI {
  @Override
  protected void init(VaadinRequest request) {
    // basic stuff
    Layout content = new VerticalLayout();
    content.setSizeFull();
    setContent(content);

    // container & grid
    BeanItemContainer<Address> container = new BeanItemContainer<>(Address.class);
    Grid grid = new Grid(container);

    // 1) either manually add nested properties and hide the actual inner bean
    container.addNestedContainerProperty("city.name");
    grid.getColumn("city.name").setHeaderCaption("City");
    grid.setColumns("street", "city.name"); // hide bean column

    // 2) or make the container create nested properties for your inner beans
    container.addNestedContainerBean("city");
    grid.getColumn("city.name").setHeaderCaption("City");

    // create some dummy data to populate the grid
    City city = new City("There");
    Address address = new Address(city, "Here");
    container.addItem(address);
    content.addComponent(grid);
  }
}
