通常、ユーザーはレポートのデータを印刷する前に、[印刷プレビュー]ダイアログを表示してドキュメントがどのように印刷されるかをプレビューする場合があります。 [印刷プレビュー]ダイアログで、ページレイアウトの異常性を確認して修正することができます。ただし、 [印刷プレビュー]ダイアログはワークシート全体のプレビューしか生成できず、特定のデータをプレビューして印刷することはできません。
Spread.Sheetsでは、印刷用のプレビューの枠線を表示して対象のデータのみを印刷できます。本機能は、大きなワークシートでの場合、異なるページに特定のデータ(またはセル範囲)のみを印刷するのに役立ちます。
ワークシートにプレビュー枠線を表示するかどうかを取得または設定するには、WorksheetクラスのisPrintLineVisible()メソッドを使用することができます。
たとえば、さまざまな地域ごとの製品の販売情報やその他の統計値を含むマーケティングのアプリケーションで作業しているとします。このような場合、地域ごとに販売データを異なるページに印刷するには、印刷用に選択されたデータが正しいページに印刷されるかどうかを確認してプレビューする必要があります。印刷用のプレビュー枠線を表示することにより、特定のページに対象のデータを正しく印刷できます。
次の図は、印刷用のプレビュー枠線を表示する例を示します。 ユーザーが開始行を「2」、開始列を「1」、終了行を「6」、終了列を「4」に設定すると、 印刷対象の領域を「B3:E7」として示すプレビュー枠線が表示されます。
次のサンプルコードは、印刷用のプレビュー枠線を表示する例を示します。
