If your source table columns happen to have some formatting applied which you intend to keep after the columns merge CONCAT_VIEW function is the best way to ensure that, allowing to not only perform the merge but also retain the original formatting of a column&cell, including links.
SELECT CONCAT(T1.'Surname'," ",T1.'Name') as 'FORMATTING LEFT',
CONCAT_VIEW(T1.'Surname'," ",T1.'Name') as 'FORMATTING RETAINED' FROM T1
