I can't for example plus tow elements of the UItable. Why????

Hi dear any body, When I want to plus tow elements of an uitable data, this below error will appear. how can I solve this problem?

the error : " Undefined function 'plus' for input arguments of type 'cell' "

I Use below command to read the table data.

dat=get(handles.tab1,'data'); n=dat(2,1)+dat(1,1);
