You can only do that if the two rows have common information - otherwise the system has no idea which row to "combine" with the other - and without that, it can't guarantee to produce the same information twice in a row.
In your example the only common data is "Paris", so just use a JOIN:
SELECT a.*, b.*
FROM Table1 a
JOIN Table2 b
ON a.ColumnWithParisIn = b.OtherColumnThatHasParisIn
