Hi, @danielepitzus! So, just to clarify, you are saying that

<th colspan="2" scope="rowgroup">Dwarf planets</th>

should be

<th colspan="2" scope="colgroup">Dwarf planets</th>

I am thinking about this (we wrote the example so long ago now). As I understand it, it should be rowgroup, as it references the thing the header is a header for (a row), not the things that it spans (columns).

You could possibly even argue that it could be changed to scope="row", as it is a header for a single row rather than a group, but it is more consistent with the rest of the table this way.
