I wrote the below code

    def prep(r):
        if (r.method == 'import'):
            ptable = s3db.pr_person
            ptable.pe_label.requires = None
        return True
    s3.prep = prep
    table = s3db.dvr_case_appointment
    return s3_rest_controller(csv_extra_fields=[{'label': 'Appointment    Type', 'field': table.type_id}, {'label': 'Appointment    Date', 'field': table.date}, {'label': 'Appointment    Status', 'field': table.status}])
