Setting data at a uitable getting this error "Values within a cell array must be numeric, logical, or char"

I have the data that are shown at the figure. Columns 1,2,5,6 and 7 are cell and columns 3 and 4 are doulbes. These data are saved in a variable and I want to set them as data of an uitable

(set(handles.uitable3, 'data', data))

However i got the following error

"Values within a cell array must be numeric, logical, or char".

What sould I do?

Those columns 1, 2, 5, 6, 7, should not be cell arrays of strings: they should be strings directly. So class(data{1,1}) should be char not cell.
