Time table plugin needed

Hi

I need to create a time table for a gym website, but the client need to be able to easily edit it. So for example there will be a heading Monday then different times during the day and what classes are on then Tuesday etc etc.. Unlike a calendar the classes will in general stay the same week after week but will probably get updated every month or so.

Is there any plugin that I could use so it would be easy for the client to update classes and times?

Thanks for your help
