title: Costume data set datatable
body: <p><strong>I have json from url like this</strong></p>
  <pre><code>{
     &quot;data&quot;:[
        {
           &quot;id&quot;:&quot;01&quot;,
           &quot;name&quot;:&quot;Some.one&quot;
        },
        {
           &quot;id&quot;:&quot;02&quot;,
           &quot;name&quot;:&quot;Some.two&quot;
        }
     ]
  }
  </code></pre>
  <p><strong>How to add costume data to show at datatabale ?</strong></p>
  <pre><code>| id | name      |     web       |
  | 01 | Some.one  | Someone.com   |
  | 02 | Some.two  | Sometwo.com   |
  </code></pre>
  <p>In this case I want to add one more table where the contents are the data from the name column plus &quot;.com&quot;</p>
