2.17 Lookup a column

Column Lookup

You can also lookup a column by constructing a Map

import com.github.marklister.collections._
val data= CollSeq(("Zesa",10,20),
                  ("Eskom",5,11),
                  ("Sars",16,13))

val lookupByColumn= (Seq("Company","Rating","FwdPE") zip data.productIterator.toSeq).toMap

lookupByColumn("Company")
res6: Seq[Any] = List(Zesa, Eskom, Sars)

lookupColumn("FwdPE")
res7: Seq[Any] = List(20, 11, 13)

Unfortunately the underlying type is a Seq[Any], which is the most specific type productIterator can return.
