Thanks for the info…. When you create a table, add this class to the table tag “table” because this is part of the theme’s table styling. So your table would look like this:
I also changed your editor-style.css file to load in the complete CSS structure and will allow your editor view to look like the front-end of your site. I did this for my latest theme and so far it seems to work well. I will add this to the next update of Preference.
