title: Changing [[ORDERINFO]] in WooCommerce PDF invoice template
body: <p>In the template for WooCommerce PDF invoices I see this piece of code <code>[[ORDERINFO]]</code>. There are others, all in double brackets. Some of the data outputted by these code is not needed on my invoices. So I want to customize it.</p>
  
  <p>In particular, I don't need the Qty, Total ex., Tax (in the product line), the Price Inc and the Total Inc columns. I just need the Product and Price ex Column. Of course do I need the totalization on the invoice, as there is: Subtotal, VAT (if applicable) and Grand Total. Shipping is not needed because the products are all downloadable.</p>
  
  <p>I really not know how and where I do that. Please advise.</p>
