Question

Answer 1

This should work for you:

  

    
Harry
  
  

    
Simon
  
  

    
Maria
  
  

    
Victory
  

The script should be placed immediately after your table. It goes through each row of your table and adds an extra cell to the beginning with the incrementing number inside that cell.
