title: Adding comment to a column using sequelize
body: <p>Is it possible to create column comments when creating a table using sequelize?</p>
  
  <p>The document <a href="http://docs.sequelizejs.com/manual/tutorial/models-definition.html" rel="noreferrer">here</a> only says that you can add a comment to a table. But how can I add a comment to each column?</p>
  
  <p>The following code doesn't work.</p>
  
  <pre><code>const Project = sequelize.define('project', {
    title: Sequelize.STRING,
    description: Sequelize.TEXT,
    comment: "This is a comment"
  })
  </code></pre>
  
  <p>The way I check whether column comment is successfully added or not is executing <code>SHOW FULL FIELDS FROM table_name</code>.</p>
  
  <p>Here's the version of my mysql server:</p>
  
  <pre><code>innodb_version  5.7.18
  protocol_version    10
  slave_type_conversions  
  tls_version TLSv1,TLSv1.1
  version 5.7.18
  version_comment MySQL Community Server (GPL)
  version_compile_machine x86_64
  version_compile_os  Linux
  </code></pre>
