슬라이서는 표 데이터를 필터링하는 새로운 방법으로 제공됩니다. 필터링 후 표에 표시되는 데이터를 명확하게 나타냅니다.

슬라이서는 표를 사용하기 때문에 슬라이서를 만들려면 먼저 표를 추가해야 합니다. 다음 코드와 같이 add 메서드를 사용하여 슬라이서를 추가할 수 있습니다: 슬라이서는 슬라이서 헤더와 슬라이서 본문으로 구성됩니다. 슬라이서 헤더는 슬라이서 캡션과 필터 지우기 단추로 구성됩니다. 슬라이서 캡션은 캡션을 표시하는 데 사용됩니다. 필터 지우기 단추는 슬라이서 필터를 해제하는 데 사용되며 기본적으로 비활성화되어 있습니다. 슬라이서 항목이 필터링된 경우에만 활성화됩니다. 슬라이서 본문은 슬라이서 항목으로 구성됩니다. 슬라이서 항목에는 다음 네 종류가 있습니다.: No Data Items: 항목이 다른 슬라이서에 의해 필터링되었습니다. Has Data Items: 항목이 다른 슬라이서에 의해 필터링되지 않았습니다. Selected Items: 항목이 항목 자체에 의해 필터링되었습니다. Unselected Items: 항목이 항목 자체에 의해 필터링되지 않았습니다. 항목은 다른 슬라이서로 필터링되는 경우 데이터 항목 없음과 데이터 항목 있음, 자체적으로 필터링되는 경우 선택한 항목과 선택되지 않은 항목으로 각각 나뉩니다.
