how can I use the function "table" in a loop when the number of input variables changes ?

Hi, how can I use the function "table" in a loop when the number of input variables var1,...,varN, in T = table(var1,...,varN) changes ?

For example, I have something similar, where I have to specify the number of columns of my matrix A to create a table:

A = [  4           0           0
      56           6           8
     164          18          40
     159          13         139];
T = table(A(:,1), A(:,2), A(:,3), 'VariableNames', {'col 1', 'col 2', 'col 3'})

However, my matrix A changes number of columns several times and I would like to find an automatic way to create tables in a loop without changing the number of table entries every time manually.. The best for me would be something like this:

for i = 1 : 5
T{i} = table(A{i}, 'VariableNames', VarNames_array)
end

Thannk a lot, exactly what I need!

array2table

T = array2table(A);

if you want to specify variable names "col#",

T = array2table(A), 'VariableNames', compose('col%d',1:size(A,2)));

Many thanks! Exactly what I need!
