This article references the use of Content Types. I covered the concept of Content Types
Page Tables are a concept that is built on top of content types. If you’ve never heard of content types you should start by reading the article listed above.
Page Tables are simply the definition of each content type offered to the content manager that will be collecting content. Once they have the content types, they then have a template for exactly what information they need to gather when developing content for the website. This enables the team member to begin collecting, organizing and formatting content before the project is even in the design phase.
