MATLAB: To combine different cells with empty columns together

cellcell arrayMATLABmatrix

Hi. I want to combine three different cells in a cell with additional empty columns..
funct1 =
    'Q7'
    'Q12F'
    'Q12G'
    'Q12H'
    'Q12I'
    'Q12L'
    'Q12M'
funct2 =
    'Q12G'
    'Q12H'
    'Q12I'
    'Q12L'
    'Q12M'
funct3 =
    'Q12G'
    'Q12H'
    'Q12I'
Final cell will become like this.
funct =
    'Q7'      []    'Q12G'    []    'Q12G'    []
    'Q12F'    []    'Q12H'    []    'Q12H'    []
    'Q12G'    []    'Q12I'    []    'Q12I'    []
    'Q12H'    []    'Q12L'    []        []    []
    'Q12I'    []    'Q12M'    []        []    []
    'Q12L'    []        []    []        []    []
    'Q12M'    []        []    []        []    []
Could anyone show me how?

fu ={{
    'Q7'
    'Q12F'
    'Q12G'
    'Q12H'
    'Q12I'
    'Q12L'
    'Q12M'};
   {'Q12G'
    'Q12H'
    'Q12I'
    'Q12L'
    'Q12M'};
  { 'Q12G'
    'Q12H'
    'Q12I'}};
n = cellfun(@numel,fu);
m = max(n);
k = numel(n);
ou = zeros(m*2*k,1);
n1 = n + 2*(0:k-1)'*m;
n0 = n1 - n + 1;
ou(n0) = 1;
ou(n1+1) = -1;
lo = cumsum(ou);
out = cell(m,2*k);
out(lo > 0) = cat(1,fu{:});
or
n = cellfun(@numel,fu);
m = max(n);
k = numel(n);
out = cell(m,2*k);
for ii = 1:k
    out(1:n(ii),2*ii-1) = fu{ii};
end
