2000-06-10  Christopher James Lahey  <clahey@helixcode.com>

	* Makefile.am: Added $(GNOME_PRINT_LIBS) to all of the LDADDs.

	* e-cell-text.c: Added printing of text cells.

	* e-cell.c, e-cell.h: Added print and print_height methods.

	* e-table-field-chooser.glade: Added a minimum size.

	* e-table-group-container.c: Fixed a rectangle sizing bug.

	* e-table-group-leaf.c: Implemented get_printable.

	* e-table-group.c, e-table-group.h: Added a get_printable method
	to return an EPrintable.

	* e-table-item.c, e-table-item.h: Added a get_printable function
	to return an EPrintable.

	* e-table.c, e-table.h: Added a get_printable function to return
	an EPrintable.
