This is an interesting observation. One possible explanation for a lack of robust first class table manipulation support in mainstream languages could be due to the large variance in real-world table sizes and the mutually exclusive subproblems that come with each respective jump in order-of-magnitude row size.

The problems that one might encounter in dealing with a 1m row table are quite different to a 1b row table, and a 1b row table is a rounding error compared to the problems that a 1t row table presents. A standard library needs to support these massive variations at least somewhat gracefully and that's not a trivial API surface to design.
