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