Book topics contain elements such as plain text, hypertext links, and imbedded graphics.
Topics have headings, like chapters in a hardcopy book.
Table of Contents A list of topics contained in a book. Tables Preformatted data, usually arranged in rows and columns, such as a grid or a spreadsheet layout. If the author specified a table list and there are tables in the book, a Tables topic will exist in the Table of Contents. Since tables are preformatted they can be larger than the viewing area and require scrolling. Figures Preformatted drawings or other illustrations, prebuilt into the book.
