Replace elements of a cell

I wrote the following code:

testcell={'R1(2)' 'R1(1)' 'R1(0)'};
vfinal = cell(4,10);
vfinal(1:3) = testcell

I was expecting that the result was:

vfinal = 
    'R1(2)'    'R1(1)'    'R1(0)'    []    []    []    []    []    []    []
         []         []         []    []    []    []    []    []    []    []
         []         []         []    []    []    []    []    []    []    []
         []         []         []    []    []    []    []    []    []    []

But the result was:

 vfinal = 
      'R1(2)'    []    []    []    []    []    []    []    []    []
      'R1(1)'    []    []    []    []    []    []    []    []    []
      'R1(0)'    []    []    []    []    []    []    []    []    []
           []    []    []    []    []    []    []    []    []    []

Any tips?

Thank you.

testcell={'R1(2)' 'R1(1)' 'R1(0)'};
vfinal = cell(4,10);
vfinal(1,1:3) = testcell
