8 – There is no token table

Note: What you refer to as the “token table” is actually a form element (named “token_tree”) that is provided by the contributed Token module. You need the contributed Token module in both Drupal 7 and Drupal 8 if you want to use this form element – it is not part of Token module functionality included in core Drupal 8, you still need the contributed Token module.

That said, Token module tokens are not used by Rules in Drupal 8. Instead, Rules uses typed-data Twig tokens, similar to how Views works. See for example https://www.drupal.org/docs/contributed-modules/d8-rules-essentials/token-replacement and related pages in that documentation guide (which includes many examples of how to use these tokens, how to find out what tokens are available, how to modify token values, etc.)
