Trouble with jquery external file

[eluser]pickupman[/eluser]
I have tested this and the table does sort as expected.

Code:

//head
//jquery src file
//jquery.tablesorter.js file
//jquery.tablesorter.css file
$(document).ready(function(){
  $("#myTable").tablesorter();
});


//body
$template = array('table_open' => '<table id="myTable" class="tablesorter" border="0" cellpadding="4" cellspacing="0">',
     'heading_row_start'   => '<tr>',
     'heading_row_end'     => '</tr>',
     'heading_cell_start'  => '<th>',
     'heading_cell_end'    => '</th>'
  );  
  $this->table->set_template($template);
  
  $this->table->set_heading('ID', 'Name');
  
  $this->table->add_row(array(1, 'Joe'));
  $this->table->add_row(array(2, 'John'));
  $this->table->add_row(array(3, 'Jeff'));
  
  echo $this->table->generate();

Unless you have copied over a css/theme file, you may think the table is not working like on the demo page, however the column headings should still sort when clicking them.
