Fixing the Font Alignment

Thank you for this wonderful plugin. It’s to-the-point & simple.

I have a slight formatting issue. The text titled ‘Weight’ & ‘Height’ is a bit off. It’s sticking to the extreme left of the table. How do I fix that?

I tried editing the CSS but not sure if I did it correctly. Do let me know how I can fix this.
