I'm using artistsC01 theme version 5.x. Apparently there is a global setting that prevents table borders from showing. I would like to determine for each table that I have, as some of the content I'm adding does require a table with borders and other content does not, whether or not each table has a border. So, I need help finding the global border setting, knowing how to undo it, and knowing where to find other borders in the theme that will need to be adjusted, such as in the header, where I don't want a border but where it will likely appear once I remove that global setting.
