Split a list into multiple columns after each x element

Hello,

Is it possible to adjust a table/matrix in a form where I split a list into multiple columns after each x element?

The goal is to avoid scrolling and give a better overview on longer lists.

Like in the example i prepared in excel below, after 10 nationalities, I would like the list to add a second column with the list ongoing and the total at the end.

Thank you for your feedback,

Best regards

Andreas
