            new Person("Johannes Kepler", 15));
     TextField txt =new TextField();
      CheckBox chk=new CheckBox();
        // Create a grid bound to the list
        Grid<Person> grid = new Grid<>();
        grid.setItems(people);
        grid.addColumn(Person::getName).setCaption("Name");
        grid.addColumn(Person::getAge).setCaption("Year of birth");

Selection via check boxes works with the multi selection mode, see docs. On the same page you can read about ComponentRenderer which allows to put any component in a column. Note that this feature is available since Vaadin 8.1. released few days ago.
