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);
...显示如此(" 201509"和" 201510"列):
我希望这些值显示为" 9月15日和#34;和" 10月15日"
在Excel Interop中,它完成了这样的操作:
var monthField = pvt.PivotFields("MonthYr");
monthField.Orientation = XlPivotFieldOrientation.xlColumnField;
monthField.NumberFormat = "MMM yy";
...但是在EPPlus中,相应的变量(monthYrColField)没有" NumberFormat" (或" Style")成员。
我试过了:
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"
如何在"未转换"中更改EPPlus中ColumnField列标题的格式?到" MMM yy"格式?
对于VDWWD:
正如您在评论中看到的那样,有很多与数据透视表相关的东西在EPPlus中无法工作或很难开始工作;与EPPlus相比,Excel Interop是一只熊(而不是泰迪熊或考拉,但更像是灰熊),但对于数据透视表来说,与Exterop相比,EPPlus似乎有点半生不熟。 -a-脆度。

您可以使用内置日期格式YearMonthPattern
。这会将september 2016
作为格式。
pivotTableWorksheet.Column(2).Style.Numberformat.Format = DateTimeFormatInfo.CurrentInfo.YearMonthPattern;
如果您真的想要MMM yy
作为模式,则需要覆盖文化格式:
Thread.CurrentThread.CurrentCulture = new CultureInfo("nl-NL")
{
DateTimeFormat = { YearMonthPattern = "MMM yy" }
};
pivotTableWorksheet.Column(2).Style.Numberformat.Format = DateTimeFormatInfo.CurrentInfo.YearMonthPattern;

似乎您不能在字段本身上设置格式。您必须通过数据透视表对象进行访问:
pivotTable.DataFields[0].Format = "MMM yy";
应用于基础工作表的任何格式似乎都被完全忽略了。
