Hi again,
I just tested this on a test site of mine, and can confirm the problem.
The @import
directive is saved, but it’s not added to the combined/minified version of the “Custom CSS”.
However, I have no idea why this is the case. My guess is that the external PHP library that TablePress uses for this either has a bug here or is removing it on purpose. I’ll have to investigate this more deeply, and therefore can not promise a quick solution. I’m really sorry.
Therefore, my suggestion would be to paste in the CSS that you wanted to import. This should also be better for performance, as it saves another HTTP request.
Regards,
Tobias
