These similar methods exist in v7.1.3.2:

new(name, default, sql_type = nil, null = true) public

Instantiates a new column in the table.

name is the column’s name, such as supplier_id in supplier_id int(11). default is the type-casted default value, such as new in sales_stage varchar(20) default 'new'. sql_type is used to extract the column’s length, if necessary. For example 60 in company_name varchar(60). It will be mapped to one of the standard Rails SQL types in the type attribute. null determines if this column allows NULL values.
