Enable cell editing in Nebula NatTable

I'm trying to learn how to enable cell editing in Nebula NatTable. I edited _301_CustomDataProviderExample::createExampleControl to show this feature:

@Override
public Control createExampleControl(Composite parent) {
    //...
    final NatTable natTable = new NatTable(parent, SWT.NO_BACKGROUND
                | SWT.NO_REDRAW_RESIZE | SWT.DOUBLE_BUFFERED, bodyDataLayer, false);

    natTable.addConfiguration(new DefaultNatTableStyleConfiguration());

    natTable.addConfiguration(new AbstractRegistryConfiguration() {
        @Override
        public void configureRegistry(IConfigRegistry configRegistry) {
            configRegistry.registerConfigAttribute(
                    EditConfigAttributes.CELL_EDITABLE_RULE,
                    IEditableRule.ALWAYS_EDITABLE);
        }
    });

    natTable.configure();

    return natTable;
}

But when run the example, I cannot edit the cells. What am I missing? Thanks!

Update: my solution for this case is:

    bodyDataLayer.addConfiguration(new DefaultEditConfiguration());
    bodyDataLayer.addConfiguration(new DefaultEditBindings());

Note: don't add those configurations to natTable cause of java.lang.ClassCastException: org.eclipse.nebula.widgets.nattable.NatTable cannot be cast to org.eclipse.nebula.widgets.nattable.layer.AbstractLayer

You are missing the necessary edit related configurations DefaultEditBindings and DefaultEditConfiguration, which will configure the editors and the bindings to react on user interaction.

This is explained in the documentation: https://www.eclipse.org/nattable/documentation.php?page=editing
