instance method CSV::Table#[]

self[index_or_header] -> object

In the default mixed mode, this method returns rows for index access and columns for header access. You can force the index association by first calling by_col!() or by_row!().

Columns are returned as an Array of values. Altering that Array has no effect on the table.
