title: Merge Cells in WPF DataGrid
body: <p>I want to create a WPF datagrid that spans over multiple rows in one column. Like this:</p>
  
  <pre><code>+-------+----------------+
  | Name  | Attributes     |
  +-------+----------------+
  |       | Horse Power    |
  | BMW   +----------------+
  |       | Color          |
  +-------+----------------+
  |       | Weight         |
  | Ford  +----------------+
  |       | Color          |
  +-------+----------------+
  </code></pre>
  
  <p>How can the following code be changed to get it done? </p>
  
  <pre><code>&lt;DataGrid AutoGenerateColumns="False"&gt;
       &lt;DataGrid.Columns&gt;
            &lt;DataGridTextColumn Header="Name" /&gt;
            &lt;DataGridTextColumn Header="Attributes" /&gt;
       &lt;/DataGrid.Columns&gt;
  &lt;/DataGrid&gt;
  </code></pre>
