Rows to Column

I have a tab delimited file like this:

1   2   3   4   5   6 
7   8   9   10  11   12 
13  14  15  16   17   18

I want it to look like:

1   7    13
2   8    14
3   9    15
4   10   16
5   11   17
6   12   18

I was thinking reading line by line into it's own array with perl, printing \n, and then pasting/appending columns next to each other. But there must be a faster way, can't awk do this easily?

                   print $y[$j]->[$i], "\t";
                 print "\n";
