Realize cells.

1999-11-25  Miguel de Icaza  <miguel@gnu.org>

	* e-table-header-item.c (ethi_realize): Realize cells.

	* e-table-item.c (eti_header_dim_changed): redraw before and after.

	* e-table-header-item.c (ethi_event): Add continuous resizing.

1999-11-24  Miguel de Icaza  <miguel@gnu.org>

	* e-table-subset.h, e-table-subset.c: New files, used to implement
	subset tables.

	* e-table-sorted.h, e-table-sorted.c: Now they derive from
	e-table-subset.

	* e-cell.c, e-cell.h: realize method now return per view instance
	data.
