Hello quincyjones,

Could you please try following and let us know if this helps.
Code:
awk '{X[$1];Y[$2];Z[$1,$2]=$3}
END{
printf "%20s",""; for(i in X) printf "%10s",i;print "";
for(j in Y) {printf "%10s",j;printf "%10s",""
for(i in X) printf "%10s",Z[i,j];print "";}
}' Input_file

Thanks,
R. Singh
