Hi,
As a further update to this... It turns out that the reason my actions were not appearing on my cells was because i had a filter on my excel report that was using a multi select. If in the filter i'd have selected ALL or just one of the list items then the action would have appeared.
This has been seen elsewhere and is blogged about here:

Anyhow, just thought i'd share my final findings because it took me several hours of fiddling and searching yesterday before finding out exactly what the problem was.
Thanks,
Simon
