title: Create a tiny integer column with custom size in Laravel migration
body: <p>How can I add tiny integer column using laravel migration to MySQL? I thought this code</p>
  
  <p><code>$table-&gt;addColumn('tinyInteger', 'birth_day', ['lenght' =&gt; 2]);</code></p>
  
  <p>But it creates TINYINT(4) column. I don't know how I can solve this problem. Please don't ask me why a day only, not full date. It is a business logic of the app.</p>
