Adding scroll bars to cells in a table

[susieq]

I want to be able to have scroll bars within a particular cell within a
table, as this table will be viewed on the web.
As one cell is going to contain considerable data, and some of the other
cells will not, I want to be able to have scroll bars to some of the cells,
thereby allowing for easy viewing for customers and also the table cell will
not take up as much room.
I managed to add a Div to one cell, but although it showed with scroll bars
in preview mode (webpage), on the design page, the cell kept on getting
longer the more data I entered.
Does anyone know the correct Div I need to add, so that it also works in
design mode on a webpage.
I also posted this question to the Frontpage group.
Thanks

This is not possible if the table is an Excel table.
