Eduardo was telling us:
Eduardo nous racontait que :

Do a catalogue (or Directory) type of merge using ony clolumn A from Excel
as the database source.
When you create the merge document, use a once cell table to put the
mergefield.
After the merge, you should end up with a one column table, each row
containing info from each cell of the A column in Excel.

Whenever you change the database, redo the merge to have an updated version
of the informatin in the merged document. (And discard the previously merged
document, or keep it as an archive...)

If you want a truely interactive document, I think you will have to manually
insert each field as I suggested in my previous post.
Maybe someone will drop by with an easy way to do this...
One way would be to copy-paste special (with link) the whole Excel range
(A2:Axx) in Word, this will be fine as long as you do not add records in the
Excel range of cells.
