          The ``destination`` setter accepts:
  
          - a :class:`~google.cloud.bigquery.table.Table`, or
          - a :class:`~google.cloud.bigquery.table.TableReference`, or
          - a :class:`str` of the fully-qualified table ID in standard SQL
            format. The value must included a project ID, dataset ID, and table
            ID, each separated by ``.``. For example:
            ``your-project.your_dataset.your_table``.
