When you create a document using eaDocX, all the formatting options you have chosen are saved inside your Word document as the Document Definition.
Each type of element, and even each stereotype of each type of element, has it's own 'profile' within the Document Definition, which says how it will be printed:
Each Profile contains:
owhich fields and tagged values are printed, and in which order
oany table column titles,
oany conditional formatting rules you have created
The profiles inside the Document Definition can be saved and shared between documents so that all your documents print in a similar style - see Sharing Document Profiles.
