Renaming Columns by Column Number

This function renames columns based on their position.

The second and third argument are lists, each with the same number of elements.

ColumnNumbers is 0-based, so the first column is 0.

let
    RenameColumns = (InputTable as table, ColumnNumbers as list, NewColumnNames as list) =>
let
    OldColumnNames = Table.ColumnNames(InputTable),
    Indexed = List.Zip({OldColumnNames, {0..-1+List.Count(OldColumnNames)}}),
    Filtered = List.Select(Indexed, each List.Contains(ColumnNumbers,_{1})),
    IndexRemoved = List.Transform(Filtered, each _{0}),
    RenameList = List.Zip({IndexRemoved,NewColumnNames}),
    RenamedColumns = Table.RenameColumns(InputTable, RenameList)
