getColumn for Table

while it's possible to get list of column KV in row, afaik it's not possible to get list of row KV in column. it'd be useful in e.g implementing board games.

Right, so let's say we have a a .getColumn(col: C) function, would this be the expected behavior?

const table = HashTableHashColumn.of(
  [1, "a", { a: 1 }],
  [2, "a", { a: 2 }],
  [2, "b", { a: 3 }]
);
const column = table.getColumn("a");
// column is a Map containing 2 entries: [1, { a: 1}] and [2, { a: 2 }]

Instead of getColumn it would probably be streamColumn so that you can choose in what kind of collection to put the result.

hmm, i was thinking of ["a", "a", "b"] for table.getColumn(1) (index) but maybe i misunderstood the table API
