          This method is used to indicate whether rendering this article's content
          will result in the creation of out-of-flow HTML tables. This method has
          a base class implementation representing a common logic; if an article
          has a graphic(image) representation of a table then the HTML
          representation will be placed out-of-flow if it exists, if there is no
          graphic(image) represenation then the HTML representation will be placed
          in-flow.
  
          Returns
          -------
          bool
              True if there are out-of-flow HTML tables, False otherwise
