ピボットテーブルの項目スライサーは、テーブルスライサーと同じように、SlicerCollection（WorkSheet.slicers）によって管理されます。
項目スライサーは、任意のフィールド（Calcフィールドを除く）に追加できます。
項目スライサーで行われた変更は、手動フィルターを使用した場合と同じで、ラベルフィルターの「textItems」を意味します。
スライサーの追加
項目スライサーを追加する場合は、まず例として「pt」という名前のピボットテーブルを作成します。 (initPivotTable の具体的な実装については、この記事の最後にあります)。
次に、「name」フィールドに項目スライサーを追加します。
項目の状態
項目は2つの状態を持つように定義しました。
selected：項目がフィルターによって選択されているかどうか。
noData：他のフィルターによって選択されている場合、つまり、選択してもしなくても効果がない場合は、noDataと定義します。
これら2つの状態によって、項目の状態が構成されます。
たとえば、"selected && noData"や"unselected && hasData"のようになります。
スライサーの使用
次に、slicer_nameを制御することができます。
たとえば、2つの列に項目を表示したい場合です。
項目の高さをより高くしたい場合
noDataの状態の項目を表示したくない場合
ピボットテーブルを作成するサンプル
項目スライサーのスタイルのカスタマイズ
SpreadJS は、ピボットテーブルの項目スライサーのスタイルのカスタマイズをサポートしています。
