The way I read the change as stated in 226.6(b)(1) is that the tabular format must be substantially similar to any of the applicable tables in G-17(FR Vol. 74 January 29, 2009, pages 5431-5434). There are 4 examples (G-17(A) through G-17(D))- I think you can select whichever format best fits your product and go from there.
Though, haven't all the Reg Z changes set forth in the Federal Register Vol 74 -5244 through 5498 published January 29, 2009 been withdrawn? See:
