Returns [database, "public", table] for a table of dataset_name or of this dataset.

Arguments:

  • table_name - Table to address, optional.
  • quote - Whether to escape each component.
  • casefold - Whether to case-fold each component.
  • dataset_name - Dataset to address instead of this one, which is how references to another dataset are qualified.
  • catalog - Catalog to address instead of the dataset. A dataset is a database here, so it already is the catalog and this replaces it.

Returns:

  • List[str] - Path components from catalog to table.
