Review comment:
We would have to make it virtual and push it down into SimpleRecordBatch
(which is ok because right now it makes O(cols) virtual calls internally
anyways). That said, from a quick grep, I don't think the method is ever used.
Table::columns has a few uses so maybe that's worth targeting. And it's
probably better to be consistent where possible.
