NPOI Real World Pivot Beispiel

Question

Ich suchte viel, aber ich endete hier diese Frage zu stellen. Es gibt keine zufriedenstellende Antwort auf meine Frage: Ich möchte ein Excel-Pivot erstellen (WorkSheet1 als PivotTable, WorkSheet2 als Datenquelle) Ich habe kein Problem beim Erstellen von DataSource aus DataTable. Es gibt jedoch kein leitendes Dokument zum Hinzufügen hierarchischer Spalten und hierarchischer Zeilen und Kennzahlen, das auf DataSource (Arbeitsblatt 2) zurückverfolgt wird. Ich bin mir ziemlich sicher Mapping erfolgt mit:

var pt = pivotSheet.CreatePivotTable(new AreaReference(new CellReference("A2"), new CellReference(rowCount, columnCount -1)), new CellReference("A1"), dataSheet); 

Aber es gibt keinen Beweis, wie hierarchische Spalten und hierarchische Reihen und Maßnahmen zur Karte.

Ich habe meine Zeit schon zu viel verschwendet, so brauche ich sehr schlecht helfen: Jede mögliche Hilfe geschätzt wird ...

Hier ist meine Lösung mit EPPlus [** ***]

Yep Datatable ist normal, Datatable, wie Sie ques ... Strom ist jede Art von Strom hängt davon ab, wie Sie wollen, es zu benutzen: In meinem Fall Memory ASP.Net MVC Antwort als Datei herunterladen erstellen ...
