Method: CSV::Table#headers

Defined in:

lib/csv/table.rb

#headers ⇒ Object

:call-seq:

table.headers -> array_of_headers

Returns a new Array containing the String headers for the table.

If the table is not empty, returns the headers from the first row:

rows = [
  CSV::Row.new(['Foo', 'Bar'], []),
  CSV::Row.new(['FOO', 'BAR'], []),
  CSV::Row.new(['foo', 'bar'], []),
]
table  = CSV::Table.new(rows)
table.headers # => ["Foo", "Bar"]
table.delete(0)
table.headers # => ["FOO", "BAR"]
table.delete(0)
table.headers # => ["foo", "bar"]

If the table is empty, returns a copy of the headers in the table itself:

table.delete(0)
table.headers # => ["Foo", "Bar"]
