[As of August 2020] You can now trigger record rules on tables while inline editing. These rules can update the record being edited, insert a new connected record, update a connected record or send a custom email.
These record rules are similar to form record rules and can be used to do things like track which user last updated a record, send an email when a record is updated or update/insert connected records when a status has changed.
