MATLAB: How to keep count of occurence of column combination using ‘for’ loop

How to check the number of occurence of pairs in the nx2 matrix A.

A = [1,1;2,1;3,1;1,2;2,2;3,2;1,3;2,3;3,3;1,1;2,1;3,1;1,2;2,2;3,2;1,3;2,3;3,3;1,1;2,1;3,1;1,2;2,2;3,2;1,3;2,3;3,3;1,1;2,1;3,1];
[unqPairs, ~, pairID] = unique(A,'rows','stable');
pairCount = histcounts(pairID,'BinMethod','integers');
T = table(unqPairs, pairCount(:), 'VariableNames', {'UniquePairs','Count'});

Result
