No, this is not how a grib table works.  What I can do is remove any 
reference to level from a parameter description.  Likewise, I can remove 
references to "monthly", "daily", and "hourly" that seem to crash 
between the various versions of the tables.  It would then be up to the 
end user to deduce that a given parameter in a file named 
"rainfall_monthly_average" or "temp_daily_average" has a particular 
meaning beyond an average value.  However, the same table cannot mean 
monthly in one dataset and daily in another.

I downloaded all of the gldas and nldas gribtab files from the webpage 
that was sent to me.  There seem to be four different tables:

-1:221:221:1
-1:173:4:130
-1:7:138:130
-1:7:12:130

Are you the owner of these tables?  I'm not sure what the leading -1 
means (unless it is the very old "discipline"), but applying the common 
Center:Subcenter:Version logic would seem to indicate that three 
different Centers (221, 173, and 7) and four different Subcenters 
(221:221, 173:4, 7:138, 7:12) are represented.
