Print Specific Columns using AWK

I'm trying to fetch the data from column B to D from a tab delimited file "FILE". The simple AWK code I use fetch the data, but unfortunately keeps the output in a single column and remove the identifiers (shown below).

Any suggestions please.

CODE

 awk '{for(i=2;i<=4;++i)print $i}' FILE

FILE

           A            B               C               D               E               F             G

Why don't you directly use cut ?

$ cut -d$'\t' -f2-4 < file
B C D

With awk you would need printf to avoid new lines of print :

awk -F"\t" '{for(i=2;i<=4;++i) printf "%s%s", $i, (i==4?RS:FS)}'
