ClosedXML - 创建多个数据透视表

Question

我正在尝试将一些数据导出到excel表,S1其数据将在接下来的两个表中显示为Pivoted视图S2 and S3.我能够创建一个单一的枢轴,它完美无缺.但是当我创建两个枢轴时,后续的Excel文件呈现为损坏.

腐败我的意思是,

点击是,我得到了 -

这是我用来创建枢轴的代码 -

using XL = ClosedXML.Excel;
...
XL.XLWorkbook wb = new XL.XLWorkbook();
dsData = Session["ExportData"] as DataSet;

var sheet1 = wb.Worksheets.Add("output table");
sheet1.Cell(1, 1).InsertTable(dsData.Tables[0], "output table", true);

// sheet1 is the reference sheet S1
var dataRange = sheet1.RangeUsed();

// First Pivot
XL.IXLWorksheet ptSheet1 = wb.Worksheets.Add("S2");

var pt1 = ptSheet1.PivotTables.AddNew("PivotTable1", ptSheet.Cell(3, 1), dataRange);


pt1.ReportFilters.Add("CX");

pt1.RowLabels.Add("C1");
pt1.RowLabels.Add("C2");
pt1.RowLabels.Add("C3");
pt1.RowLabels.Add("C4");

pt1.ColumnLabels.Add("CL1");
pt1.ColumnLabels.Add("CL2");
pt1.ColumnLabels.Add("CL3");

pt1.Values.Add("V").SummaryFormula = XL.XLPivotSummary.Sum;


// Second Pivot
XL.IXLWorksheet ptSheet2 = wb.Worksheets.Add("S3");

var pt2 = ptSheet2.PivotTables.AddNew("PivotTable2", ptSheet1.Cell(3, 1), dataRange);

pt2.ReportFilters.Add("QQ");

pt2.RowLabels.Add("C1");
pt2.RowLabels.Add("C2");

pt2.ColumnLabels.Add("CL1");
pt2.ColumnLabels.Add("CL2");
pt2.ColumnLabels.Add("CL3");

pt2.Values.Add("V").SummaryFormula = XL.XLPivotSummary.Sum;

C1, C2, C3. C4 and V是我的参考表中的列名S1.

该问题是由ClosedXML实现错误引起的.

通过使用以下代码段(其数据透视表示例的修改版本)并在Excel中打开生成的文件,可以轻松地重现它:

static void CreateTestPivotTables(string filePath)
{
    var wb = new XLWorkbook();

    var wsData = wb.Worksheets.Add("Data");            
    wsData.Cell("A1").Value = "Category";
    wsData.Cell("A2").Value = "A";
    wsData.Cell("A3").Value = "B";
    wsData.Cell("A4").Value = "B";
    wsData.Cell("B1").Value = "Number";
    wsData.Cell("B2").Value = 100;
    wsData.Cell("B3").Value = 150;
    wsData.Cell("B4").Value = 75;
    var source = wsData.Range("A1:B4");

    for (int i = 1; i <= 2; i++)
    {
        var name = "PT" + i;
        var wsPT = wb.Worksheets.Add(name);
        var pt = wsPT.PivotTables.AddNew(name, wsPT.Cell("A1"), source);
        pt.RowLabels.Add("Category");
        pt.Values.Add("Number")
            .ShowAsPctFrom("Category").And("A")
            .NumberFormat.Format = "0%";
    }

    wb.SaveAs(filePath);
}

该错误位于XLWorkbook_Save.cs中 - GeneratePivotTables方法:

private static void GeneratePivotTables(WorkbookPart workbookPart, WorksheetPart worksheetPart,
    XLWorksheet xlWorksheet,
    SaveContext context)
{
    foreach (var pt in xlWorksheet.PivotTables)
    {
        var ptCdp = context.RelIdGenerator.GetNext(RelType.Workbook);

        var pivotTableCacheDefinitionPart = workbookPart.AddNewPart<PivotTableCacheDefinitionPart>(ptCdp);
        GeneratePivotTableCacheDefinitionPartContent(pivotTableCacheDefinitionPart, pt);

        var pivotCaches = new PivotCaches();
        var pivotCache = new PivotCache {CacheId = 0U, Id = ptCdp};

        pivotCaches.AppendChild(pivotCache);

        workbookPart.Workbook.AppendChild(pivotCaches);

        var pivotTablePart =
            worksheetPart.AddNewPart<PivotTablePart>(context.RelIdGenerator.GetNext(RelType.Workbook));
        GeneratePivotTablePartContent(pivotTablePart, pt);

        pivotTablePart.AddPart(pivotTableCacheDefinitionPart, context.RelIdGenerator.GetNext(RelType.Workbook));
    }
}

由线workbookPart.Workbook.AppendChild(pivotCaches);,其增加了多个PivotCaches对workbookPart.Workbook,而它的允许包含0或1.

话虽如此,修复它的唯一方法是在源代码中修改上面的方法,如下所示:

private static void GeneratePivotTables(WorkbookPart workbookPart, WorksheetPart worksheetPart,
    XLWorksheet xlWorksheet,
    SaveContext context)
{
    var pivotCaches = workbookPart.Workbook.GetFirstChild<PivotCaches>();
    foreach (var pt in xlWorksheet.PivotTables)
    {
        var ptCdp = context.RelIdGenerator.GetNext(RelType.Workbook);

        var pivotTableCacheDefinitionPart = workbookPart.AddNewPart<PivotTableCacheDefinitionPart>(ptCdp);
        GeneratePivotTableCacheDefinitionPartContent(pivotTableCacheDefinitionPart, pt);

        if (pivotCaches == null)
            workbookPart.Workbook.AppendChild(pivotCaches = new PivotCaches());
        var pivotCache = new PivotCache { CacheId = (uint)pivotCaches.Count(), Id = ptCdp };
        pivotCaches.AppendChild(pivotCache);

        var pivotTablePart =
            worksheetPart.AddNewPart<PivotTablePart>(context.RelIdGenerator.GetNext(RelType.Workbook));
        GeneratePivotTablePartContent(pivotTablePart, pt);
        pivotTablePart.PivotTableDefinition.CacheId = pivotCache.CacheId;

        pivotTablePart.AddPart(pivotTableCacheDefinitionPart, context.RelIdGenerator.GetNext(RelType.Workbook));
    }
}

更新:好消息是我的帖子引发了ClosedXML源库修复由弗朗索瓦·博塔(还称赞到petelids谁把它在那里),所以你可以从那里乘坐代码,直到他们的下一个版本,其有望将其纳入.
