> Currently, the pivot() function accepts the pivot column as a string. It is not consistent to groupBy API and causes additional problem of using nested columns as the pivot column.
> `Column` support is needed for (a) API consistency, (b) user productivity and (c) performance. In general, we should follow to the POLA - https://en.wikipedia.org/wiki/Principle_of_least_astonishment in designing of the API.
