Another solution for you.

#!/usr/bin/perl -w
use strict;

my @RowNames;
my @Columns;

while (<DATA>)
{
    my $i=0; 
    my ($name, @row)= split;
       
    push @RowNames, $name;
    push @{$Columns[$i++]}, $_ for (@row);    
}

foreach my $cref (@Columns)
{
   foreach my $name (@RowNames)
   {
      print "$name\t",shift @$cref,"\n";
   }
}

=prints
foo1    1
foo2    2
foo3    3
foo1    4
foo2    5
foo3    6
foo1    7
foo2    8
foo3    9
=cut

__DATA__
foo1    1    4    7
foo2    2    5    8
