Yes it can ask; and if the switch can’t do so it will reply with an error.

Assume that a switch initially has only table 0. Can controller ask switch to add another table (table 1) with some specific features?

The controller can use this message to request a new pipeline (set of new tables) from the switch. Also, there is ongoing work in ONF on Table Type Patterns (TTPs) [1]. These are predefined pipelines that the controller and switch can negotiate before starting the OpenFlow channel. Comparing these in their current state I think TTPs are more mature; also TTPs provide additional information on the tables that the switch can use for optimized table implementations.
