title: sqlalchemy Integer column size
body: <p>I saw somewhere that you can define a column size for Integer columns (e.g. Integer(20), Integer(10), etc.) but for some reason, it seems that sqlalchemy ignore those sizes in the create table query it produces through create_all():</p>
  
  <pre><code>class Job(Base):
      __tablename__ = "t_job"
  
      id = Column(Integer(20), Sequence('%s_id_seq' % __tablename__), primary_key=True, nullable=False)
      name = Column(String(30))
      company_id = Column(Integer(20), ForeignKey("t_company.id", ondelete="CASCADE"), nullable=False)
  </code></pre>
  
  <p>Produces the following query:</p>
  
  <pre><code>CREATE TABLE t_job (
          id INTEGER NOT NULL AUTO_INCREMENT,
          name VARCHAR(30),
          company_id INTEGER NOT NULL,
          PRIMARY KEY (id),
          FOREIGN KEY(company_id) REFERENCES t_company (id) ON DELETE CASCADE
  )
  </code></pre>
  
  <p>If that's not a proper way to do this, what is?</p>
