Describe the bug

An error is raised for map_headers on a DataTable if one header value is a prefix of another header value.

To Reproduce

# RuntimeError Exception: 2 headers matched "ant": ["ant", "anteater"]

Expected behavior
[{"Ant"=>1, "Anteater"=>2}]

Same issue

RuntimeError Exception: 3 headers matched "name": ["name", "short_name", "full_name"]

Is there a solution? Or a better way to map the headers?
