Name
       DTIF - Digital Table Interchange Format

Description
       Digital	Table Interchange Format (DTIF) is the standard format for the storage and interchange of documents that contain data tables, for-
       mulas, and spreadsheets. You can use DTIF to store and retrieve database information, interchange spreadsheets, and reference table data in
       compound documents.

       DTIF defines the logical structure and physical layout of a data table, the values within the table (absolute data and/or expressions), and
       presentation attributes (formatting) to be used when displaying or printing the table. DTIF works with Digital Document Interchange  Format
       (DDIF) so that you can store or reference DTIF tables in DDIF-encoded compound documents.

       A  DTIF	document  can  contain	a sequence of one or more tables and is uniquely identified by a product name, a version number, and other
       descriptive information such as the document's title and creation date.	Each DTIF table is a 2-dimensional display of  data  values  orga-
       nized in columns and rows that has its own structure and table data stored in cells.

       In  DTIF  documents,  attributes  specify  the  type  and format of information pertaining to the data stored in a table. Column attributes
       describe information for all the cells in a particular column, whereas generic column attributes can be applied to any column in any  table
       that  references  them. Format attributes define the printed and displayed presentation of data stored in the table.  Format attributes can
       also be redefined at the window, column, or cell level.
