> While tables and struct type columns are semantically equivalent (and tables can be embedded
in other tables using struct types), the memory layout of a table may not be strictly contiguous.
For the purposes of putting data on the wire / in shared memory, it may be useful to offer
a conversion function to "structify" an in-memory logical Arrow table. See ARROW-24
