Probably don't need to call this directly. Calling is_downloading with a
param automatically sets table as downloadable.

@param bool $downloadable optional param to set whether data from
table is downloadable. If ommitted this function can be used to get
current state of table.
@return bool whether table data is set to be downloadable.
