Please open GitHub issues (or PRs) for any tables you'd like to added! If there is a cost API then we'd definitely like to have a table to query it. In the meantime, you may find the "Thrifty" mods useful - they have many prebuilt queries to look for cost saving opportunities in AWS, Azure, GCP and DigitalOcean - https://hub.steampipe.io/mods?q=thrifty
