I have a table with many columns and can not get them all on a form that is
set up by rows. Any suggestions on how to handle the additional columns.
If you have more than 25 or 30 fields (they're called fields, not columns
usually) in a table - then your table is almost certainly misdesigned. Access
is NOT A SPREADSHEET, even though a table might look like one!
What are some of these fields? What is the nature of the data you are storing?
I very strongly suspect that you have a one-to-many or many-to-many
relationship embedded within each record, and that normalizing your data will
be a far better solution than tweaking your form.
