I see, Kim.
For now, I'm using only the comment tag "<!-- ..... -->" enclosing the code inside of each cell in order to make the content invisible:
HTML Code:
' <td class="dataTableContent" align="right" valign="top"> <!-- <strong>' .
$currencies->format(zen_add_tax($order->products[$i]['final_price'], $order->products[$i]['tax']), true, $order->info['currency'], $order->info['currency_value']) .
($order->products[$i]['onetime_charges'] != 0 ? '<br />' . $currencies->format(zen_add_tax($order->products[$i]['onetime_charges'], $order->products[$i]['tax']), true, $order->info['currency'], $order->info['currency_value']) : '') .
'</strong> --> </td>' . "\n" .
Also, regarding the headers, I changed each definition using blank spaces instead of the original value:
PHP Code:
define('TABLE_HEADING_PRICE_EXCLUDING_TAX', ' ');
That way, headers and content are not removed but they are now invisible.
I'm aware that the mine is a "home remedy" 
but it works!
Thanks to you I didn't miss editing the invoice.php where the changes must be done too.
These are the paths:
admin/includes/languages/english/orders.php
admin/includes/languages/english/invoice.php
admin/orders.php
admin/invoice.php
I appreciate your support.
