How to get the values of a popupmenu that is embedded in an individual cell in a uitable?

I have a uitable with multiple rows and columns. Some of the cells contain numeric values while others have popupmenus with multiple string selections. My question is how can I get the values of a popupmenu that is embedded in an individual cell in a uitable?

Could you provide us with a small example uitable?
