To
...
return
...
an
...
{{AutoFilter}}
...
object,
...
use
...
[Worksheet.AutoFilter|Worksheet.AutoFilter].
...
There
...
is
...
only
...
one
...
auto
...
filter
...
per
...
worksheet;
...
by
...
default,
...
the
...
filter
...
is
...
not
...
set
...
and
...
[AutoFilter.Area]
...
will
...
return
...
{{null}}.
...
When
...
applying
...
an
...
auto
...
filter
...
to
...
a
...
select
...
area
...
of
...
cells
...
on
...
a
...
worksheet,
...
bear
...
in
...
mind:
...
#
...
[AutoFilter.Area]
...
must
...
be
...
set
...
to
...
an
...
[Area]
...
object
...
on
...
the
...
same
...
worksheet
...
as
...
the
...
auto
...
filter.
...
#
...
There
...
is
...
only
...
one
...
auto
...
filter
...
per
...
worksheet.
...
If
...
[AutoFilter.Area]
...
is
...
already
...
set,
...
changing
...
{{AutoFilter.Area}}
...
will
...
overwrite
...
the
...
previous
...
area
...
and
...
the
...
auto
...
filter
...
will
...
be
...
applied
...
to
...
the
...
new
...
area.
...
#
...
{{AutoFilter.Area}}
...
must
...
include
...
all
...
of
...
the
...
cells
...
that
...
the
...
filter
...
applies
...
to.
...
ExcelWriter
...
will
...
not
...
automatically
...
detect
...
the
...
boundaries
...
of
...
the
...
filtered
...
area.
...
The
...
filter
...
will
...
be
...
removed
...
from
...
the
...
worksheet
...
either
...
by
...
calling
...
the
...
filter's
...
[Clear()|AutoFilter.Clear()]
...
method,
...
by
...
setting
...
the
...
{{Area}}
...
property
...
to
...
{{null}},
...
or
...
by
...
deleting
...
all
...
the
...
rows
...
(or
...
just
...
the
...
first
...
row
...
that
...
has
...
the
...
filter
...
headers)
...
or
...
all
...
the
...
columns
...
of
...
the
...
filter
...
from
...
the
...
worksheet.
