title: Add Custom Header in Pentaho
body: <p>I have data that looks like the following:</p>
  
  <h2>assetnum | assetdesc</h2>
  
  <p>123      | sampledesc</p>
  
  <p>432      | sample desc2</p>
  
  <p>I want to insert another row with four fields so it looks like the following:</p>
  
  <p>SYSNAME  | OBJSTRUC | AddChange | En</p>
  
  <h2>assetnum | assetdesc</h2>
  
  <p>123      | sampledesc</p>
  
  <p>432      | sample desc2</p>
  
  <p>However I am unsure how to do this. Does anyone know how?
  I have tried generating rows but I am unsure how to merge so that it looks like this. I have also thought of adding headers but I am unsure how to specify the header (without it being created automatically) I am quite new to Pentaho. 
  Thanks. </p>
