Since you haven't mentioned, I will assume that it's a fixed-format file -

Code:
$
$
$ cat f0
NAME1     NAME2     ADDRESS   TEL
name001   name002   addr001   tel001
name011   name022   addr011   tel011
name111   name222   addr111   tel111
$
$
$ awk 'NR==1{printf("%-10s%-10s%-10s%-10s%-10s%-s\n","ID",$1,$2,"EMAIL",$3,$4)}
       NR>1 {printf("%-10s%-10s%-10s%-10s%-10s%-s\n"," ",$1,$2," ",$3,$4)}
      ' f0
ID        NAME1     NAME2     EMAIL     ADDRESS   TEL
          name001   name002             addr001   tel001
          name011   name022             addr011   tel011
          name111   name222             addr111   tel111
