Vaadin 8 Grid filtering

The Vaadin 8 Grid documentation mentions use of filtering, but fails to include any examples! In fact, I've noticed a couple of places where features are mentioned but there is no mention of how to implement or an example. IMHO - the documentation for Vaadin 8 is pretty poor, lacking in solid examples and contains mistakes.

For example, the Filtering section in 
mentions grid.setDataProvider(johnPersons);
however there is no JohnPersons!!

How can we implement SIMPLE grid column based filtering without using a DataProvider?

I think that the filter is done on dataProvider, so you need a dataprovider to filter your table.
In the documentation, perhaps you just have to change johnPersons --> wrapper.
If you want to filter a simple list, you can do something like that (to filter on multiple criteria:

private TextField filterColumn1;
    private TextField filterColumn2; // you can use Combobox<String> ...
    private Grid<YourObject> yourObjectGrid;
    private ConfigurableFilterDataProvider<YourObject, Void, SerializablePredicate<YourObject>> filterYourObjectDataProvider;
    public Grid<YourObject> getYourObjectGrid() {
        if (yourObjectGrid == null){
            yourObjectGrid = new Grid<YourObject>();
            ListDataProvider<YourObject> dataProvider =  new ListDataProvider<YourObject>(getAllYourObjects()); // your List<YourObject>
            // filter list by custom filter
            filterYourObjectDataProvider = dataProvider.withConfigurableFilter();
            // refresh data when value changed
            filterColumn1.addValueChangeListener(e -> {refreshyourObjectGrid();});
            filterColumn2.addValueChangeListener(e -> {refreshyourObjectGrid();});
        return yourObjectGrid;
    private void refreshyourObjectGrid(){
    private SerializablePredicate<YourObject> filterYourObjectGrid(){
        SerializablePredicate<YourObject> columnPredicate = null;
        columnPredicate = yourObject -> (yourObject.getColumn1().equals(filterColumn1.getValue()) && yourObject.getColumn2().equals(filterColumn2.getValue()));
        return columnPredicate;

Thank you for your suggestion. I took your comments and created FilterableGrid which wraps a standard Grid and allows me to set text filters for string based fields.
