in thread Statistics via hash- NCBI BLAST Tab Delimited file

I don't think Text::Table is the right tool for this application. It is only really useful for about a page worth of reading. Your first column will be 75 plus ? spaces alone. How do you plan to view the data? A couple of ideas that occured to me would be to create a comma separated values file or use Perl6::Form (like I did in Re: Formatting text, eg long lines). (You could wrap that long first column so it wouldn't run across the page).

With a comma separated values file format, you could open the files in Excel, (if you are on a Windows machine), and, if there is a large dataset, (more than a couple of pages), you can freeze the headers in Excel while still scrolling your data.

If your results will have many lines of results, with Perl6::Form, you could arrange headers to print after so many lines.

I say that about Text::Table because I'm guessing your results will be more than a couple of pages. If not, Text::Table would be OK.

If there are alot of rows to print, you might want to print your header for every (50?) lines or so to aid your readers. A way to do it below:

Instead of print $tb at the end of your script, the following would repeat the header every 50 lines. 

my $rows = $tb->body_height(); 
$pagelines = 50;

for my $i (0 .. $rows-1) {
    print $tb->title() if $i % $pagelines == 0;
    print $tb->body($i);
    print "\n" if $i % $pagelines == $pagelines-1;
}

Update: set rows to the number of rows in table.
I was getting the number of items from keys %freq.
