* A type-invariant immutable Table of row key type R, column key type C, and value type V.
* In the Table, a combination of a row and column key has exactly one value.
* See the [Table documentation](https://rimbu.org/docs/collections/table) and the [HashTableHashColumn API documentation](https://rimbu.org/api/rimbu/table/hash-row/HashTableHashColumn/interface)
* @note
* - The HashTableHashColumn uses a HashMap to map row keys to column.
* - The HashTableHashColumn uses HashMaps to map column keys to values.
* @typeparam R - the row key type
* @typeparam C - the column key type
* @typeparam V - the value type
* @example
* ```ts
* const t1 = HashTableHashColumn.empty<number, string, boolean>()
* const t2 = HashTableHashColumn.of([1, 'a', true], [2, 'a', false])
