Pages 13.1 (7037.0.101) Mail Merge into label template

I'm on Macbook Retina, 12-inch, Early 2016) using Montrerey 12.6.9

Can you wonderful folk please advise how I add the fields from my Numbers names & addresses list on to my Avery labels table template? (The objective is A4 sheets each of 12 labels, every cell unique; ie., with the first then subsequent records from the spreadsheet.)

After no success getting the merge facility working within the table, I inserted an unformatted page and added the merge fields, then tried copying and pasting those fields to one cell of the table. Even changing paragraph marks to "new line" marks didn't prevent the program treating each field as a separate record and as such using a cell for each line.
