title: Append a column to an existing Datatable with dynamically bound values
body: <p>I have the following Datatable in Vb</p>
  
  <pre><code>   Id            Price
    -----          -------
     1231           100
     1232           150
     1235           150
  </code></pre>
  
  <p>I want to add a third column to that datatable called <code>flag</code>, with values of the last digit of <code>Id</code></p>
  
  <p>Like the following:</p>
  
  <pre><code>    Id               Price         Flag
     -----            ------       ----------
      1231             100             1
      1232             150             2
      1235             150             5
  </code></pre>
  
  <p>How do I append a column to an existing Datatable, with dynamically bound values?</p>
  
  <p>Is there a way I can do this without using a For Loop?</p>
  
  <p>Any help would be appreciated</p>
