Maybe you should take a look at this bundle SonataExtraAdminBundle

It provides some extra features for Sonata such as image type in list field, or string template.

protected function configureListFields(ListMapper $listMapper)
{
    $listMapper
        ...
        ->add('fullname', 'string_template', array(
            'string_template' => '<span class="pull-right">{{ object.firstname }} {{ object.lastname }}</span>'
        ))
    ;
}
