title: Add data row to datatable at predefined index
body: <p>I have a datatable with one column:</p>
  
  <pre><code>this.callsTable.Columns.Add("Call", typeof(String));
  </code></pre>
  
  <p>I then want to add a row to that datatable, but want to give a specific index, the commented number is the desired index:</p>
  
  <pre><code>this.callsTable.Rows.Add("Legs"); //11
  </code></pre>
  
  <p>Update:</p>
  
  <ul>
  <li>Must be able to handle inputting hundreds of rows with unique
  indexes. </li>
  <li>The index must be what is defined by me no matter if there are enough
  rows in the table or not for the insertat function.</li>
  </ul>
