Table within a Cell of another Table

Hello.
Is it possible to create a table within a cell of another table?

Ideally, a field with a Datatype of Table

No quite such a data type, sorry!

What is possible is having a larger table with references to a smaller table, and creating linked views (e.g. select student, see their schedule as a table per-student, even though the schedule is actually a larger table that covers all students).

Another thing that’s possible is a Reference List, where a single cell can contain a list of references to another table.

Finally, with Python formulas you can create fairly arbitrary values, including Python objects or table-like text. E.g. see the computed “Full List” column in the “Bill Of Materials Card” here: Restaurant Custom Orders - Grist
