有谁知道如何做到这一点？

我在 .Net 中使用 EPPlus，并创建了一个包含 2 个行字段和一个汇总数据字段的数据透视表：

Dim Pivot As OfficeOpenXml.Table.PivotTable.ExcelPivotTable
Pivot = wksPivot.PivotTables.Add(wksPivot.Cells("A1"), Datarange, "pName")

Pivot.RowFields.Add(Pivot.Fields("Fld1")).Sort = Table.PivotTable.eSortType.Ascending
Pivot.RowFields.Add(Pivot.Fields("Fld2")).Sort = Table.PivotTable.eSortType.Ascending

Dim dtaFld As OfficeOpenXml.Table.PivotTable.ExcelPivotTableDataField
dtaFld = Pivot.DataFields.Add(Pivot.Fields("XYZ"))
dtaFld.Function = Table.PivotTable.DataFieldFunctions.Sum

一切正常，但我希望数据透视表在用户打开工作簿时以折叠状态开始（在 excel 中，当您创建数据透视表时，您可以右键单击数据元素并选择“展开/折叠" > "折叠整个字段"

热我可以通过代码做到这一点吗？（如果 EPPlus 还不支持，我愿意直接使用 OpenXML ......）

另外，有没有办法从工作簿中删除原始数据，以便数据透视表仍然有效？我试过了，当我打开工作簿时，我的数据透视表是空白的？- 我目前的逻辑让我想到了这个问题......有什么想法吗？

（我确实知道我在 VB 中写了这个问题。但我在这个问题中添加了C#&VB标记 - 我对任何一种语言的代码都很满意 - 谢谢！！）

可以使它成为 xlsm 并向其添加 vba。这可能是这个解决方案最糟糕的答案，但它实现了完全崩溃。我提供了一个工作示例，只需将过去复制到一个新的控制台应用程序中即可。添加 epplus 依赖项“F5”。

使用 EPPlus，您可以尝试类似（取自这篇 SO 帖子）：

(from pf in pivot.Fields
 select pf).ToList().ForEach(f =>
 {
     f.Compact = false;
     f.Outline = false;
 });

或者更简单地说，像下面这样的东西不工作吗？

pvtTable.Compact = False
pvtTable.CompactData = False
pvtTable.Outline = False
pvtTable.OutlineData = False
pvtTable.ShowDrill = True

另请查看这篇 SO 帖子，详细介绍了一种很好的逆向工程方法，用于了解 excel 如何实现“事物”。

PS无法帮助您解决其他“也”问题，抱歉。
