Each Clay table has a 70 column limit total. Of those 70 columns, up to 30 can be action or integration columns (enrichment columns). If you implement a waterfall, the integration column limit increases to 40. [1]
On Enterprise plans, you get 40 action columns per table instead of the standard 30.
If you need any more help with column limits or anything else in Clay, just let me know. Would you like to share more about what you're trying to achieve with your table?
