Sir, can your provide some direction as to where this table can be found?
The current S&W manual can be downloaded as a PDF from the S&W web site. It no longer contains the chart included in earlier versions, however it does state on page 11 that +P ammunition should NOT be used in K-frame revolvers manufactured prior to 1958. +P can be used in "numbered" model K-frames.
The chart included in earlier versions of the manual only indicated standard pressure .38 special ammunition as suitable for use in J-frames, regardless of when they were manufactured.
