Adding td classes when using .rows.add()

robert_sinton

I'm using the className option for columnDefs when initialising my tables, but I've noticed that if I add row data using .rows.add(), the TDs in those rows don't get the classnames added.

Is there a simple way to ensure this happens? The end goal is to make some columns in my table right-aligned, but the tables start out empty when initialised, and data is added dynamically later.
