Hi Chris,

When you're dealing with table fields, the actual data
is stored not only in the field text, but also in two
separate custom poperties of the field :
  the cREVTable["currentview"]
  the cREVTable["formattedview"]

And of course the revTable frontScript works with
these internal data structures rather than the actual
text of the field, and will happily overwrite the text
with its own data when it gets a chance?

Now how do we use this knowledge ?
  -- build the (unformatted) data for the table
  --  column per column, row by row
  --  note that it wants an extra return at the end
  put "1" & tab & "foo" & return & \
      "2" & tab & "bar" & return into tTableData
  -- update the 'basic' table data :
  set the cREVTable["currentview"] of field "snafu" \
      to tTableData
  -- and tell it to format our data and redraw
  revDisplayFormattedData field "foobar"

Hope this helped,

Jan Schenkel.
