Add multiple repeatable zones in a slice

Hello @marina

Welcome to the Prismic community and thanks for reaching out to us.

To answer the first part of your question, it's possible to create a table by using the repeatable zone of Slices. We have a nice article on the same, which shows multiple ways to create a table in Prismic.

To answer the second part of your question, to see the data of the linked content, you need to adjust your API query with the graphQuery option. Once you adjust the API query the linked content will appear in a "data" object nested in the Link or Content Relationship field.
Would you please follow this document for Template Content in Next.js - Documentation - Prismic?

I'd recommend you to go with my first solution to create a table in Prismic.

Let me know what do you think about it.

Thanks,
Priyanka
