This creates a table. Once it is created, edit some of the cells until you are content.
T = uitable('data',magic(3),'columnedit',true(1,3));
Now, to get the data, do:
D = get(T,'data');
If you only need some of the data, index into D. For example, to get the entire second row:
D2 = D(2,:);
or to get the entire second column:
D2 = D(:,2)
