Add `Map` transform #187

Closed eliascarv closed 1 year ago

eliascarv commented 1 year ago

The Map transform applies a function to table columns using the map function. The following codes are equivalent:

table |> Map([:a, :b] => ((a, b) -> 2a + b) => :c)
table.c = map((a, b) -> 2a + b, table.a, table.b)
