New function that returns the total minimum width of all the columns.

2002-03-15  Christopher James Lahey  <clahey@ximian.com>

	* e-table-header.c, e-table-header.h (e_table_header_min_width):
	New function that returns the total minimum width of all the
	columns.

	* e-table.c, e-table.h (set_header_width): Call
	e_table_header_min_width here instead of total_width.
	(et_size_request): Override the size_request method instead of
	doing set_usize.
