Index column and deferRender

Axela

I have a table where I would like to add a column where the user could see row indexes, like in this example. The problem is that the table has quite a bit of rows and expected to be accessed from mobile so, as one would expect, I'd like to have it loading as fast as it's possible. One of ways to make it faster is to use deferRender option which really improves loading speed but it's not compatible with the code for index column because it generates IDs only for first page.

So, I was wondering if there is some other lightweight approach to add that column while keeping deferRender on. My guess would be to utilize column render mechanics but I can't find a way yet to access indexes of rendered rows from there.
