Ckeditor how to highlight table fields in editor?

Question

CKEditor

Hello.
Ckeditor how to highlight table fields in editor?

Shows transparent by default. (in theory, without using border 1, I would like to see something, the outlines of the borders in order to navigate well, or do you still advise forcibly turning on somehow so that border 1 is set when copying forms). At the front, I normally do everything through styles, but in the editor, if there is no border, then everything is transparent.



What is the best way to solve this problem?
