I don't know if this needs to be done in this PR, but we could also swap the position between the output table and the map.

Thank you for the PR. As there is nothing in the issue, not sure what you planned to fix here and if my comments are pertinent. But as you started to change some styles, I followed your lead :)

[theocrsb]

The left spacing of the map is good but now we need to align all item with it 🙂
