Explain this migrate line?

Rails
1

So I have this code in a migration file …

create_table :books do |t|
  t.column  "Title",  :string
  t.column  "Price",  :decimal
  t.timestamps
end

Are “Title” and :string just parameters being passed to the method
t.column?

If so, I understand that “Title” is a string parameter, what
is :string? a type param?

Thanks

Title : name of the column
string : type of the column. it maps to varchar/varchar2

Similarly for Price
