Once you have the table, you can build a tree and then call $table_tree->as_HTML:
in reply to Question on extracting HTML tables with HTML::TableExtract
You can also call tables() to get a list of all the tables and then put a loop around the above.
use HTML::TableExtract qw(tree);
my $te = HTML::TableExtract->new();
my $table = $te->first_table_found;
my $table_tree = $table->tree;
my $table_html = $table_tree->as_HTML;
You need to have the optional HTML::TreeBuilder and HTML::ElementTable installed for this to work.
