Hi James,
To my knowledge there is no such thing as a "standard" GRIB1 table format. NCEP, ECMWF, and wgrib all use different orderings for the columns. And unfortunately I guess so does NCL. The order you have will not work. NCL's format is described at http://www.ncl.ucar.edu/Document/Manuals/Ref_Manual/NclFormatSupport.shtml#GRIB1-user-defined-parameter-tables.
Basically the order needs to be:
Param number : abbreviation : units : descriptive name
You can change the separator character and you can use spaces as long as there are at least 2 spaces between the column entries and never more than 1 space between the words of the descriptive name or the units characters. The separator is determined by the table header row that begins with a -1 in the parameter number column.
The abbreviation cannot have any spaces and must contain only letters, numbers or the underscore character.
