Witt transform examples in the OEIS

[Jonathan Post]

So, Richard Mathar, is it worth your submitting the matrix, read by
antidiagonals
A[k,n] = n-th value of k-th Witt transform of A000012
which begins:

.......|..n=0.|.n=1.|.n=2.|.n=3.|.n=4.|.n=5.|.n=6.|.n=7.|.n=8.|
k=1.|....1...|...1...|....1..|....1..|...1..|...1...|...1...|.....1..|...1..|.
k=2.|....0...|...1...|....1..|....2..|...2..|...3...|...3...|....4...|...4..|.
k=3.|....0...|...1...|....2..|....3..|...5..|...7...|...9...|...12...|.15..|.
k=4.|....0...|...1...|....2...|...5..|...8..|..14..|..20...|..30...|..40.|.
k=5.|....0...|...1...|....3...|...7..|.14..|..25..|..42...|..66...|..99.|.
k=6.|....0...|...1...|....3...|...9..|.20..|..42..|..75...|.132..|.212.|.
k=7.|....0...|...1...|....4...|.12..|.30...|.66..|.132..|..245.|.429.|.

and so forth?

Anything to say about the columns?

And what is the main diagonal?

This might help with problems about reconciling the offsets from one
row to another, as it were.

Of course, this 2-D-ization can be done to iterated Witt transforms of
other initial sequences...
