@newperson

Thanks for your help and example. I did Google this for hours, and found only something similar to your idea on stackoverflow.com. Your example works well for certain things, but it doesn't do what I want which is to apply css to the tr or the td, rather than just inserting html. And it also doesn't work for setting the background colour.

afterInsertRow might be a better approach and I'll explore that. Thanks. You might like to add newperson's example to your docs since I'm sure that will help a lot of people (just not what I want to do here). Ideally, I wanted to apply a style to the tr so that certain rows are bold or have a different background, depending on the value of one column. So afterInsertRow may do the trick.
