Delete a cell, row or column. These objects are fetched using
table<-cell, table<-row
or table<-column.
Deleting rows or columns holding spanned cells will deal naturally
with these cells: There location and spanning will be updated such that
they span the same set of rows/columns.
If keep is @on,
the content of the row, column or cell are kept. Otherwise the content
is visual->destroyed.
If a column is deleted, all cells that will be deleted from the table
are attached to the table_column
object. Together with
table->insert_column,
this allows for relocating columns if a table without loosing the
table-properties. Note that the column should be object->lock_object’ed
to avoid destruction by the incremental garbage collector. The following
code moves column 4 to be the first column:
...
get(Table, column, 4, Col),
send(Col, lock_object, @on),
send(Tbale, delete, Col, @on),
send(Table, insert_column, 1, Col),
send(Col, lock_object, @off),
...
See also table->insert_column, table->insert_row,
table->append, table_cell->row_span
and
table_cell->col_span.
