title: Delete tableview column at index
body: <p>I'd need to remove all columns from a table except the first two. 
  I am Iterating over the table columns and am stuck at the part where I have to delete the column based on the index.</p>
  
  <p>So far I have this:</p>
  
  <pre><code>int x;
  for (x = 2; x &lt; [table numberOfColumns]; x++) {
      [table removetablecolumn:([table column:x])]
  
  }
  </code></pre>
