Question

我收到此错误：

This command requires at least two rows of source data. You cannot use the command on a selection in only one row. Try the following:

- If you're using an advanced filter, select a range of cells that contains at least two rows of data. Then click the Advanced Filter command again.
- I you're creating a PivotTable, type a cell reference or select a range that includes at least two rows of data

间歇性地对这行代码：

xlWorkBook.RefreshAll();

有两个工作表。一个有一个数据透视表，一个有原始数据。有时只有一行数据。对于多行数据，上方的代码行始终有效;但是，对于仅一行数据，上面的代码有时有效，有时我会收到上面的错误消息。

除此之外，包含数据透视表的工作表是不刷新;但是，如果我重新打开文件，它也不刷新，除非我手动显式刷新它。

这里发生了什么？为什么我有时只会收到此错误？

非常感谢你的指导。

如果有帮助，我将包括整个方法：

Answer 1

我可以使用数据透视表复制此错误的唯一方法是尝试在没有列标题的范围内创建一个，就像Stephan1010的答案截图一样。

在 GetPivotData Excel函数中，数据透视字段的名称由=GETPIVOTDATA("EmailAddress",$A$3)）引用;因此，禁止不具备它们的数据源是有意义的。

当您选择范围ListObject和格式为表时，解决方案是在Excel中Range而不是$A$1:$C$1上进行转换（来自功能区），结果表将跨越$A$1:$C$2;第一行的内容成为列标题，第二行是有效的空记录。有趣的是，无论您是否检查“我的表有标题”复选框，都会发生这种情况（2行跨度）（数据将移动到第一行，表格将包含默认的“Column1” - “Column2” “ - ”如果清除复选框，则为Column3“标题。

换句话说，ListObject 总是是数据透视表的有效数据源，而Range可能不包含足够的行。此外，如果您没有列标题并且创建了范围为$A$1:$C$2的数据透视表，则$A$1:$C$1处的记录将用作列标题，这意味着第一条记录将丢失。

根据您提供的代码，我假设数据透视表已经存在并连接到包含宏的模板工作簿中的某个[named？]范围。将范围转换为表可能与从功能区中选择格式为表一样简单。然后，您可以使用这样的代码删除所有不必要的行，同时仍保留数据透视表的有效数据源：

    public void DeleteExtraTableRows(string emailAddress, Excel.ListObject table)
    {
        try
        {
            var rowIndex = 0;
            var wasDeleted = false;
            while (rowIndex <= table.ListRows.Count)
            {
                if (!wasDeleted) rowIndex++;
                var row = table.ListRows[rowIndex];

                var range = (Excel.Range)row.Range.Cells[1, 1];
                var value = range.Value2;

                if (value != null && !string.Equals(emailAddress, value.ToString()))
                {
                    row.Delete();
                    wasDeleted = true;
                }
            }
        }
        catch (Exception e)
        {
            MessageBox.Show(e.Message + "\n\n" + e.StackTrace);
        }
    }

还有可能在循环的email条件中找不到if (cell.Value2.ToString() == email )，这最终会删除范围内的所有行 - 即使唯一的区别是内单元值的结束。使用上面的代码，即使删除了所有电子邮件地址，数据源仍然是与其连接的数据透视表的有效数据源。

编辑：在Excel中，您可以通过选择相关范围并点击主页标签中的格式为表格功能区按钮，将Range变为ListObject 。或者你可以创建一个这样的：

            var range = ((Excel.Range)(worksheet.Range[worksheet.Cells[1, 1], worksheet.Cells[3, 1]]));
            var table = worksheet.ListObjects.Add(SourceType: Excel.XlListObjectSourceType.xlSrcRange, Source: range,
                                      XlListObjectHasHeaders: Excel.XlYesNoGuess.xlYes);
            table.TableStyle = "TableStyleMedium3";

在代码中，您可以使用ListObjects属性访问工作表上的所有ListObjects：

        var worksheet = (Excel.Worksheet) Globals.ThisAddIn.Application.ActiveSheet;
        var tables = worksheet.ListObjects;

然后，您可以通过几种不同的方式访问特定的ListObject /表：

        var myTable = tables[1];
        var myTable = tables.Item["Table1"];
        var myTable = tables.OfType<Excel.ListObject>().FirstOrDefault(t => t.Name == "Table1");

当从表中添加行时，它引用的实际范围将相应地扩展;使用myTable.Range访问相关范围。

我认为这种情况是因为您获得的数据透视表而发生的。导致刷新全部也将触发数据透视表的刷新命令。看下面的代码。它可能会让你对它有所了解。它肯定不是一排。我检查了它的翻转工作就好了它最可能由枢轴表引起的。

Microsoft.Office.Interop.Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application();
Microsoft.Office.Interop.Excel.Workbook xlWorkbook = xlApp.Workbooks.Open("some.xlsx");
// For each worksheet we got
foreach (Microsoft.Office.Interop.Excel.Worksheet worksheet in xlWorkbook.Sheets) 
{   // and each pivot table in each worksheet
    foreach (Microsoft.Office.Interop.Excel.PivotTable pivot in worksheet.PivotTables())
    {   // disable BackgroundQuery
        pivot.PivotTableWizard(BackgroundQuery: false);
    }
}
// try to refresh all sheet
try { xlWorkbook.RefreshAll(); } catch { }
// then save
xlWorkbook.Save();

Answer 3

显而易见的答案似乎是有时你有一行数据作为数据透视表的来源而有时候你没有 - 即使你认为你还是这样。我无法创建数据透视表（或将数据透视表的源更改为一行数据）：

PivotTableErrorExplanation

但如果你能够以某种方式找到一种方法来做到这一点，那么你已经找到了答案。从实际/理论的角度来看，没有理由不能将一行数据作为源，但看起来excel试图阻止这种情况发生（可能因为代码假设有两行）。所以如果你找到了办法，那么它可能就是一个错误。祝你好运。

此命令至少需要两行源数据
