What happened?

when generate from this table

CREATE TABLE `demo` (
  `type_double` double(11,2) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci

result below

from sqlalchemy import Column, Double, MetaData, Table

metadata = MetaData()


t_demo = Table(
    'demo', metadata,
    Column('type_double', Double(11, True)) # this code  absolutely not working
)

according the code, this is a hack for postgresql float , but didn't check dialect
