Roger,
I'm wondering if Autocrat is the tool you are looking for? You can publish a sheet or include it on a page on a Google Site. Either way, the most recent information is available. Well, a published document is only updated every five minutes.
To get around the formatting issue you can use the Text function to format the data the way you want it displayed.
A PDF will not be updated. You can include a link to the data in the PDF and the link would point to the most recent data.
The latest version of Google sites is not that hard to learn.
