Need info on Triggers

Hi
 I have a table with many columns( x,y,z). I need to capture changes to the table. I need to capture changes only for(x) some specific columns, but not
for all columns. for ex: I need to capture updates for column x, but not for columns y & Z. I also need to capture deletes from the table. I know that i have to write a trigger to capture changes to the table. my question is wether one trigger is enough to capture changes to various columns or i need one trigger each to capture changes. please advise. any additional input on triggers is welcome

please send replies if possible to the following address praveen_andugula_at_nt.com

thanks
