Multi-rows Footer

Test case: http://cochin.us/foo
I have read everything in this forum about multi-row issue including: https://www.datatables.net/forums/discussion/16866/how-can-we-have-multiple-rows-in-the-footer-of-a-datatable

I do put the column total into the 1st row cell but I need to put this total into the second row instead. My question is how do I put the column total into the second row cell of footer.

Thanks,
