TableComponent drill down

Hi, I need you help.

I would say how I can implement a table component CDF for a YQM hierarchy in order to first visualize the total over the year, and then clicking on it the four quarter have been displayed and than the month.

I know how to pass the click event and the listener, but I don't know how to update the same table with the furtether column for the further field and of course the others rows.

I hope someone could help me.

Thanks.
