27 // WPXTable: an intermediate representation of a table, designed to be created
28 // "ahead of time". unlike wordperfect's table definition messages, this representation
29 // is _consistent_: we can always count on the messages being sent using this representation
30 // (once it is created and finalized) to be reliable (assuming no bugs in this code!) :-)
31 //
32 // example situation where this might be useful: WordPerfect allows two cells,
33 // side by side, one with border, one without-- creating a false ambiguity (none
34 // actually exists: if one cell does not have a border, the other doesn't either)
