If it is only numeric data and a and b are of the same dimensions this should work:
c = a{:,:} + b{:,:}
for example:
a1 = randi(10,5,1);
a2 = randi(10,5,1);
Ta = table(a1, a2)
b1 = randi(10,5,1);
b2 = randi(10,5,1);
Tb = table(b1, b2)
c = Ta{:,:} + Tb{:,:}
gives:
Ta =
5×2 table
a1 a2
__ __
2 9
9 7
6 4
6 6
2 5
Tb =
5×2 table
b1 b2

1 5

c =
