I prefer Adam's method :
although if you want to multiply table with matrix then=>
arrayfun(@(x) A{:,x}*B(x),1:numel(B),'un',0)

Why all the complications with cell arrays and tables? Just use numeric arrays:
A = [0.2 0.5 0.3; 0.1 0.1 0.3];
B = [2;3];
C = A.* B;
or
C = bsxfun( @times, A, B );
if you have an older version of Matlab.
