What are the users trying to accomplish? "Look at data in a table" is rarely actually the reason someone is looking at a table. They are trying to gain information in order to... what?

Your best UX is going to depend on how those questions are answered. Like you said -- cards are one option to step away from tables. There may be others. But take a step back and understand the underlying problem that the table solves, then see if there is an alternative approach.
