using 1.99.2 SQLFORM.grid...
I don't see the need for this statement...
line 1641: if not searchable and not rows: return DIV(T('No records
found'))
If it was removed a user would see an empty grid rather than just a
div, no matter what the value of 'searchable' was.
An empty grid allows the user to add a record, which seems more usable
than the 'No records found' result when searchable=False
