Rails - Oct 2008 - Wrong number of arguments (2 of 0)

I''m new with RoR.
I have a simple migration file:
class CreateClubs < ActiveRecord::Migration
  def self.up
    create_table :clubs do |t|
        t.columns :name, :string
      t.columns :ref, :string
      t.columns :description, :string
      t.columns :local, :string

      t.timestamps
    end
  end

  def self.down
    drop_table :clubs
  end
end

But I get this error message:

[..]
Wrong number of arguments (2 of 0)
./db/[..].rb:4:in ''columns''
[..]

What am I missing?
Thank you for your help.

Juste before trying to migrate thie table clubs, I did it fine with 
league:

class CreateLeagues < ActiveRecord::Migration
  def self.up
    create_table :leagues do |t|
      t.columns :name, :string
      t.columns :ref, :string
      t.columns :description, :string
      t.columns :category, :string

      t.timestamps
    end
  end

  def self.down
    drop_table :leagues
  end
end
