The 2nd column

Answer 1

First of all, you need to remove the headerText attribute from the column and add a header facet inside it:

/*  no_of_sessions = Number of 
 Sessions  */

    
        
    
    ...

The escape="false" is relevant so html is escaped, then you can put anything you want in there. If you just want to style content, this is not needed
