 assertThat(table).row().value().isNull();

      Example where the assertion verifies that the value in the first Column of the Row at end point of the first Change is null : 

       
 assertThat(changes).change().rowAtEndPoint().value().isNull();
      Returns:
      this assertion object.
      Throws:
