How to export to PDF without grid in calc

I read a couple of Q&A posts and their solutions didn’t help. I looked around the settings but couldn’t find anything either.

Here is an image for reference, left is what the document looks like in calc and right is what it looks like after being exported as PDF. I just want the borders present in the doc in calc to be present in the PDF as opposed to the grid outline. Is this possible?

File if anyone wants to download & try:
Invoice 192000.ods



untick Format -> Page -> Tab: Sheet -> Section: Print -> Option: [ ] Grid

Tested using LibreOffice:

Version:; Build ID: 747b5d0ebf89f41c860ec2a39efd7cb15b54f2d8
CPU threads: 8; OS: Linux 4.12; UI render: default; VCL: kf5; 
Locale: en-US (en_US.UTF-8); UI-Language: en-US; Calc: threaded

Hope that helps.
