How to remove reference column (=1st column) from products table in order confirmation email in 1.7.6.1

[coffeejunkie]

Hello,

can anybody tell me how to remove first column from {products} table in prestashop order_conf email in PS 1.7.6.1?

Also, where to edit column width in {products} order detail table - when I change order_conf.html it has no effect. Table dimensions are given by inline styles:

<tr style="background-color:#EBECEE;">
  <td style="padding:0.6em 0.4em;width:15%;"></td>
  <td style="padding:0.6em 0.4em;width:30%;"></td>
  <td style="padding:0.6em 0.4em;width:20%;"></td>
  <td style="padding:0.6em 0.4em;width:15%;"></td>
  <td style="padding:0.6em 0.4em;width:20%;"></td>
</tr>

But I have no idea where these styles come from as it is not from classes/PaymentModule.php as most likely was in earlier versions as I've read.
