%N Triangle read by rows: T(n,k) is the number of compositions of n with maximal up-step <= k; n>=1, 0<=k<n.
%C T(n,k) is the number of compositions [p(1), p(2), ..., p(k)] of n such that max(p(j) - p(j-1)) <= k.
%C Rows are partial sums of rows of A225084.
%C The first column is A000041 (partition numbers), the second column is A003116, and the third column is A224959.
%C The diagonal is A011782.
