Event Listener

Event Listener

Now I am learning catalyst event listener, I created a event function which is to send mail whenever it is triggered by event. Then i create a new rule in component event listener , that configures whenever a table in datastore is modified, the event function get triggered and mail is sent. But it sends mail for every modifications that occur in that row but i want to send mail if there is any changes in particular column of that row. Is there any option to achieve it?
