3160199 - How can I add a table to the process documentation?

I need to be able to add a table to the step documentation so that I can give appropriately formatted guidance to the process user. This could be in the rich text editor or a custom attribute which will let me have a different table structure for different process steps. The problem with adding a custom attribute, it needs to be set globally for the columns that are in the table for all process steps. There are different column requirements for different steps. Is there a way to do this without adding several custom attributes depending on the table format?
