There are several techniques from creating css styles to pre-made reuseable table Snippets to creating table templates. Some of these techniques depend on the version of RoboHelp you are using. For example, RoboHelp 8 has brand new Table Style Templates and a Style Editor to modify them.
So,first, tell us which version of RoboHelp are you using and we can go from there.
Thank you both for responding.

I appreciate the input.
