    Fix the existence check in DataTable Column
    
    Previously DataTable Column checks whether a field exists or not
    by checking a result of dict.get(). This has a side effect that
    the check complains a field does not exist even when the field
    value is None. This commit change the logic to use hasattr to
    handle a field with None.
