tabindex and sorting

I'm creating a table with form input elements in every table cell for editing data on a large scale. The requirement I have is the tabindex goes up and down, not left and right. I can easily set this up for the initial load of the page, the problem is it all goes out the window on a sort.

So my question is, is there a way to iterate through the visible elements to assign a new tabindex to each input element after each sort?
