Not sure if this helps but I 'cleaned' up the tags with this regex to remove the 3D's

s/(class|rowspan|style|colspan)=3D/$1=/g;

#!perl
use strict;
use HTML::TableExtract;
my $infile = 'test.htm';
open IN,'<',$infile or die "$!";
open OUT,'>','clean.htm' or die "$!";
my $html;
while (<IN>){
  s/(class|rowspan|style|colspan)=3D/$1=/g;
  print OUT $_;
  $html .= $_;
}

my @col = ('Column_1','Asset Tag','Washed Number','Asset Name','Cust C
+ode','Primary IP Address');
my $te = HTML::TableExtract->new( headers=>[@col],keep_headers => 1  )
+;
$te->parse( $html );

foreach my $ts ($te->tables) {
  print "\nLine 0 ", join(', ',$ts->row(0));  
  print "\nLine 1 ", join(', ',$ts->row(1));
  print "\nLine 2 ", join(', ',$ts->row(2));
  print "\nLine 3 ", join(', ',$ts->row(3));  
  print "\nLine 4 ", join(', ',$ts->row(4));  
  print "\n";
}
