"Assessment wanted: for Structuring planet data"

Here is my link to the assessment. Please give me feedback for my code and let me know if I passed the assessment with all conditions fulfilled. Thanks.

Hi @Arthur_Chen, and thank you for sending in your code!

This looks pretty much perfect — well done on some great work!

The only small thing I noticed is that <th colspan="2"> could probably do with a scope="row" attribute, as it is also a heading that sits on top of a row.

Thanks for the feedback!
