2001-02-13  Christopher James Lahey  <clahey@ximian.com>

	* e-table-header.c, e-table-header.h
	(e_table_header_update_horizontal): This new function updates the
	minimum width of all of the columns based on the data contained in
	that column.

	* e-table.c, e-table.h (changed_idle): Added a
	horizontal_scrolling field.  Call e_table_header_update_horizontal
	if the model changes at all and horizontal_scrolling is set to TRUE.
