Hi there @zenya!
I have looked through your code, and it loooks really good. Well done on some great work.
If you look at my version, there are a couple of small differences, but nothing really major:
- Iâve used the
scope="rowgroup"
attribute on all headers that span multiple rows. - I wasnât sure why you included an asterisk (
*
) after âDwarf planetsâ.
