HTML Preview vs PDF Preview

I created the additional element as a score record table in the internal assessment and I added this element to my report, it still doesn’t show up in my PDF preview? It only shows up on my HTML.
What is the difference between HTML preview and PDF preview? How can I show my score recording table when I generate the report?

In the below file, you can see what I was trying to do.

Please help me if you have any idea about this. Thank you very much

Hi Pheak, I’d be interested to see the template code, if you’re able to share the twig file (you may have to zip it for the forums to accept the filetype). Looking at the code would help indicate what the issue might be. The HTML and PDF views can sometimes be different because the PDF rendering library does not support the full set of HTML tags and CSS classes.
