to add custom script in hobbit & also drop undesirable column

Hi,

can anyone tell me how to drop some of the default columns that displayed on the web page against host name? ( I don't want to display "SSH","ports","procs" columns). I also want to monitor another functionality(client side) using the ext script. can anyone please let me know step by step procedure. what can i modify from client side and what should i modify from server side? I tried to search a lot but could not get the desired answer that can be worked out.. :(

Please help me!
