ClosedXML透视表SetCalculation

Question

我正在尝试使用ClosedXML来导出数据与枢轴表。我能够用下面的代码创建pivot表，但是SetCalculation给我带来了一些麻烦。我想取每年金额栏之间的差额。Excel工作表无法加载并使所有Excel崩溃。

var pt = worksheet.PivotTables.AddNew("PivotTable", worksheet.Cell(rowIndex+3, 1), table.AsRange());

pt.ReportFilters.Add("Department");
pt.ReportFilters.Add("Month");
pt.ColumnLabels.Add("Year").SetCollapsed();
pt.RowLabels.Add("Account").SetCollapsed();
pt.RowLabels.Add("Description").SetCollapsed();
pt.Values.Add("Amount", "Amount").NumberFormat.NumberFormatId = 4;
pt.Values.Add("Diff","Diff").SetBaseField("Year").
SetBaseItem("Amount").SetCalculation
(XLPivotCalculation.DifferenceFrom).NumberFormat.NumberFormatId = 4;

Answer 1

我想出来了：

"Diff%").SetCalculation(XLPivotCalculation.PercentageDifferenceFrom).SetBaseField("Year").SetCalculationItem(XLPivotCalculationItem.Previous).NumberFormat.NumberFormatId = 10；
