title: Variable repeater columns
body: <p>I have an objectdatasource which i want to bind to a repeater.
  the problem is, I cannot work out how to display a variable amount of columns with a variable amount of rows.</p>
  
  <p>for example:</p>
  
  <p>The dataset I have is structured like this. The objectdatasource is a <code>List&lt;item&gt;</code>.</p>
  
  <pre><code>item {
    string name;
    List&lt;itemdata&gt; data;
  }
  
  itemdata {
    DateTime year;
    double amount;
  }
  </code></pre>
  
  <p>so basically i want to make a table</p>
  
  <pre><code>      |  year  |  year  |  year  |  year
   name | amount | amount | amount | amount
   name | amount | amount | amount | amount
   name | amount | amount | amount | amount
   name | amount | amount | amount | amount
  </code></pre>
  
  <p>The number of items are variable, as well as the number of itemdata that the item contains.</p>
  
  <p>Hope someone can point me in the right direction.</p>
  
  <p>Thanks</p>
