How to save data of different size or type in a table on GUI?

Hello! I'm working in a GUI where I want to have an Image and a Table where I can see properties of some image's object. With the Image I have no problem, my problem is the table. I have all the information about the object in a struct save in a file (.mat). I get this information searching the number of objects in the image and then, studying these. I can find 1,2,3 or more objects, according to the image. I have tried to use 'Table' selecting this from the figure (from the list on left), but I have to specify the number of rows, and columns (columns are 5 always, it isn't a problem). I need a variable number of rows , according to the number of objects. So, I decided use 'uitable'. The problem of the variable rows was solved, but now I have one more important, the type of data, and I can't solved that searching in help a lot of differents options. I need one of my columns accepts a different type, not another type but another size. I convert my struct to cell because I need it if I want to work with 'uitable', but my column number five is the object's position, so I have [x y], not only a number... I don't know if I have had explained very well, so I put part of my code, and to pictures where you could see the error what I have and what I want to put in my table (an example). Thanks you!

load todalainformacion
todaslasimagenes;
info=todaslasimagenes(1).imagen
filas=length(info);
columnas=5;
nombrescolumnas={'Area','Max','Min','Media','Cent'};
datos=struct2cell(info)
w=cell(filas,5);

for i=1:filas
    columnadatos=datos(:,i);
    filadatos=columnadatos';
    w(i,:)=filadatos;
end

pos1=get(handles.uipanel1,'Position');

t=uitable('ColumnName',nombrescolumnas,'Data',w,'Units','characters','Position',pos1);
