title: How to define a class for table to control the style of table rows
body: <p>I'm wondering if I can define a class that could also control the row styles within the table.</p>
  
  <p>Lets say I define a class "aTable"</p>
  
  <pre><code>.aTable
  {
    width:800px;
    border-spacing:2px;
  }
  </code></pre>
  
  <p>I also want to define the row styles. So when I assign this class to a table, all the rows in that table would follow the design, let say background-color:#e9e9e9;</p>
