I duplicated the main report message from this PR: https://github.com/ruby/csv/pull/4
The basic idea is that now we can delete only one column using #delete

csv_table.delete("PassengerId") csv_table.delete("Survived") csv_table.delete("Name") csv_table.to_csv

The best working way for me to do it with multiple columns:
to_del = ["Name", "Ticket"] csv_table = datus.by_col!.delete_if { |name, values| !to_del.include? name}

But maybe it should work like this?
to_del = ["Name", "Ticket"] data.delete(to_del)
