I removed some fields from <table> dialog window as here is demonstrated (dialogDefinition...), especially cellspacing, cellpadding and border. Then I expect, that if <table> from any source (web, Word...) is pasted, this attributes are disabled. But I always have border="1" etc. in HTML code. How to force editor to remove this unused attributes on paste?
I tried to use Allowed Content Rules, but editing config.allowedContent destroy/need to write all rules for all tags and extraAllowedContent does not override previously defined rules. I want to disable only a few attributes for one tag, not to write all new rules for whole editor.
