How to modify DataTable table after it's constructed

Question

I would like to modify a YUI DataTable as ajax queries get completed. So for example, i have 4 ajax queries querying for things which takes anywhere from 1s to 10s to complete. I would like to start constructing the table when the 1s query finish, and modify the table again every time a ajax query finishes. Is there a recommended way of doing this in general?

In particular, i would like to change how the column is formatted to display any potential errors that occurs while processing a row. However, the error processes slowly, so it would be beneficial to display the data first and then add on the errors later.

Thanks a lot for any help!
