title: Display left value only once
body: <p>I've got two tables (customer, purchase).  I've joined these two tables via the customerid key.  This works great.  My table looks like:</p>
  
  <pre><code>Cust_Name | Purchase $
  Mike          2.00
  Mike          3.00
  Mike          4.00
  Mike         10.00
  Mike         30.00
  </code></pre>
  
  <p>But what I would  like to display is the <code>Cust_name</code> only once (left table) and keep the display of <code>Purchase $</code> the same.  So it would look like:</p>
  
  <pre><code>Cust_Name | Purchase $
  Mike          2.00
                3.00
                4.00
               10.00
               30.00
  </code></pre>
  
  <p>How do I go about doing this?</p>
