Today I'm going to share with you a plugin that I've been working the last days. I've developed responsive table plugin since there were not a simple yet useful table responsive solution for CKEditor 4.
The idea behind it was to have a regular table on desktop and a stacked table style at mobile.
Resize the browser to see it in action.
When you add a new table you can select "basic styling" option to provide a default style or just add a table as is and later style it using basic-theme.css as example.
Please fell free to use it and add any issue at github :)
