Dear all, can anybody help with the following issue?

I have a mail merge function that takes data from an Access file and put them in a 2-column table.
This table has several tens (up to some hundreds) of lines, but is very narrow (maximum width not exceeding 20 mm).
I would like to:

1) automatically split the table at the end of each page, avoiding splitting of cells, which I suppose should be easy.

2) automatically arrange horizontally the chunks of the original table so that they will use all the space of each page. That is: each of my A4 pages should contain up to 5 pieces of the original table arranged each aside the other (with an empty space between them).
The results should be similar that I would have writing a plaint text in a word document with columns.
Cells are meant to be printed and cut out as labels.

Thanks for any suggestion
