Adjusting displayed row numbers

Hi,

The grid displays the row numbers under column 1. Is there way I can set those values myself?
I want to do server-side paging, and I need to adjust the row number accordingly (rowNum = rowNum + substart).
Would there be a way to generate the row numbers with a starting index?

Thanks!

You just need to add this
obj.setRowText(function(i){return substart + i});
