title: SQL multi layer headers
body: <p>Is there any way I can create multi layer headers in a table? For example. I am planning to create report for last month report but in output header I want "Last month report" header and sub header "server" and "application" </p>
  
  <pre><code>______________________________________________
     Last Month Report    |  Last year report   |
  ________________________|_____________________|
  Server   |   Application| Server   | Apps     |
  ________________________|______________________
  xyz      |     tomcat   |....      | .....    |
  abc      |     apache   |....      | .....    |
  ....     |     ......   |....      | .....    |
  </code></pre>
  
  <p>is it possible to create above headers layout ?</p>
