Just turn it off after you're done:
db.table.field.represent = lambda v: v[:10] + '...'
grid = webgrid.WebGrid(...)
output = grid()
db.table.field.represent = None
Also you can do:
def shorten_field(r,fieldtype, row):
if fieldtype=='datarow':
find your field and shorten it
grid.row_created = shorten_field
