title: Laravel 5.5 set size of integer fields in migration file
body: <p>I am new to laravel.</p>
  
  <p>Now i am using the migrate command to make a table, but the length of the filed is not applicable. Laravel does not provide this option. ?</p>
  
  <p>Below is my codes:</p>
  
  <pre><code>$table-&gt;increments('id')-&gt;length(11);
  $table-&gt;dateTime('created_time');
  $table-&gt;integer('bank_id')-&gt;length(11);
  $table-&gt;tinyInteger('is_black')-&gt;length(1);
  </code></pre>
  
  <p>The length of the field <code>is_black</code> should be 1, but it is actually being generated as 4.
  How can I solve this problem ?</p>
  
  <p>Any suggestion or advice would be appreciated.</p>
  
  <p>Thank you in advance</p>
