As I mentioned there is certain CSS that is not respected by the built-in PDF conversion. In my case it was page breaks. The only option then is to use one of the third party connectors to do the conversion. I've had good luck with Encodian. They have a free license that can be used to explore the possibities. I would try their connector and see if you get the results you want. If you do you'll either need to use a third party converter or modify your table styling to supported CSS.
