我在 EPPlus 中创建一个列字段,如下所示:
// Column field[s]
var monthYrColField = pivotTable.Fields["MonthYr"];
pivotTable.ColumnFields.Add(monthYrColField);
...显示如下(“201509”和“201510”列):
我希望这些值显示为“Sep 15”和“Oct 15”
在 Excel 互操作中,它是这样完成的:
var monthField = pvt.PivotFields("MonthYr");
monthField.Orientation = XlPivotFieldOrientation.xlColumnField;
monthField.NumberFormat = "MMM yy";
...但在 EPPlus 中,相应的变量 (monthYrColField) 没有“NumberFormat”(或“Style”)成员。
我试过这个:
pivotTableWorksheet.Column(2).Style.Numberformat.Format = "MMM yy";
...但是,虽然它没有抱怨或造成严重破坏,但也没有改变“201509”和“201510”的vals
如何将 EPPlus 中 ColumnField 列标题的格式从“未转换”更改为“MMM yy”格式?

对于 VDWWD:
正如您在评论中看到的,有很多与数据透视表相关的东西在 EPPlus 中不起作用或难以使用;与 EPPlus 相比,Excel Interop 是一只熊(而不是泰迪熊或考拉,但更像是一只灰熊),但对于数据透视表,与 Exterop 的炸得酥脆的相比,EPPlus 似乎有点半生不熟.
