fix this routine.

1999-12-09  Miguel de Icaza  <miguel@gnu.org>

	* e-table-header.c (e_table_header_col_diff): fix this routine.

1999-12-04  Miguel de Icaza  <miguel@gnu.org>

	* e-table-header-item.c (ethi_event): Started drag and drop
	support.

	* e-table-item.c (eti_table_model_changed): The columns are
	controled by the Header, not by the TableModel.

	* e-table-header-item.c (ethi_draw): Fixed redraw logic to support
	arbitrary header positioning.

	* e-cell.h: Revamped e-cell interface.  We now provide the model
	column and the view column to all methods (so that the methods can
	talk to the view and to the model at the same time).

	* e-table-item.c: Update to new API
	* e-cell-test.c: Update to new API

1999-12-03  Miguel de Icaza  <miguel@gnu.org>

	* e-cell.c (e_cell_class_init): Provide emtpy methods for
	enter_edit, and leave_edit.

	* e-table-item.c: Killed draw cell.
	(eti_draw): Perform column mapping here.
	(e_table_item_leave_edit): ditto.
	(e_table_item_enter_edit): ditto.
	(eti_event): ditto.
