Question

我正在创建一个在内存上生成excel的示例程序。该程序已经生成了excel，但是我无法将该表工作...

程序：

public class Program
{
    static void Main(string[] args)
    {
        CreateCurrentAccount();
    }

    static void CreateCurrentAccount()
    {
        byte[] _buffer = ExcelGenerator.CurrentAccount.GetExcel();
        File.WriteAllBytes("CurrentAccount.xlsx", _buffer);
    }
}

ExcelGenerator类：

public class ExcelGenerator
{
    static uint? _generalStyle = 0;
    static uint? _dateStyle = 1;
    static uint? _currencyStyle = 2;
    static uint? _percentageStyle = 3;
    static int maxStyleSheetName = 31;

    public static class CurrentAccount
    {
        static uint? _headerStyle = 4;
        static uint? _tableHeaderStyle = 5;
        static uint? _totalHeaderStyle = 6;

        public static byte[] GetExcel()
        {
            using (MemoryStream ms = new MemoryStream())
            {
                SpreadsheetDocument spreadsheet;
                Worksheet worksheet;

                spreadsheet = OpenXML.CreateWorkbook(ms);

                // styles
                OpenXML.AddBasicStyles(spreadsheet);
                AddAdvancedStyles(spreadsheet);

                string styleSheetName = ("Conta Corrente" /* + customer.Name*/);
                OpenXML.AddWorksheet(spreadsheet, styleSheetName.Length > maxStyleSheetName ? styleSheetName.Substring(0, maxStyleSheetName) : styleSheetName);
                worksheet = spreadsheet.WorkbookPart.WorksheetParts.First().Worksheet;

                // Sheet 1 Header
                OpenXML.MergeTwoCells(worksheet, "A1", "F1");
                OpenXML.SetCellValue(spreadsheet, worksheet, 1, 1, CellValues.String, "Conta Corrente", _headerStyle, true);

                // Header Table
                OpenXML.SetCellValue(spreadsheet, worksheet, 1, 3, CellValues.String, "Tipo de Doc.", _tableHeaderStyle, true);
                OpenXML.SetCellValue(spreadsheet, worksheet, 2, 3, CellValues.String, "Nr. Doc.", _tableHeaderStyle, true);
                OpenXML.SetCellValue(spreadsheet, worksheet, 3, 3, CellValues.String, "Valor Doc.", _tableHeaderStyle, true);
                OpenXML.SetCellValue(spreadsheet, worksheet, 4, 3, CellValues.String, "Valor Pendente", _tableHeaderStyle, true);
                OpenXML.SetCellValue(spreadsheet, worksheet, 5, 3, CellValues.String, "Data Registo", _tableHeaderStyle, true);
                OpenXML.SetCellValue(spreadsheet, worksheet, 6, 3, CellValues.String, "Data Vencimento", _tableHeaderStyle, true);

                // Table
                var currentAccountData = GetData();

                uint rowIdx = 4;
                foreach (var item in currentAccountData)
                {
                    OpenXML.SetCellValue(spreadsheet, worksheet, 1, rowIdx, CellValues.String, item.TypeDoc, _generalStyle, true);
                    OpenXML.SetCellValue(spreadsheet, worksheet, 2, rowIdx, CellValues.String, item.NrDoc, _generalStyle, true);
                    if (item.DocValue != null)
                        OpenXML.SetCellValue(spreadsheet, worksheet, 3, rowIdx, Convert.ToDouble(item.DocValue), _currencyStyle, true);
                    if (item.PendingValue != null)
                        OpenXML.SetCellValue(spreadsheet, worksheet, 4, rowIdx, Convert.ToDouble(item.PendingValue), _currencyStyle, true);
                    if (item.RecordDate != null)
                        OpenXML.SetCellValue(spreadsheet, worksheet, 5, rowIdx, item.RecordDate, _dateStyle, true);
                    if (item.SalaryDate != null)
                        OpenXML.SetCellValue(spreadsheet, worksheet, 6, rowIdx, item.SalaryDate, _dateStyle, true);

                    rowIdx++;
                }

                TableParts tableParts1 = new TableParts() { Count = (uint)1U };
                TablePart tablePart1 = new TablePart() { Id = "rId1" };
                tableParts1.Append(tablePart1);
                worksheet.Append(tableParts1);

                OpenXML.CreateTable(spreadsheet, worksheet, "table1", 3U, 1U, (uint)currentAccountData.Count + 3, 6U);
                TableDefinitionPart tableDefinitionPart1 = worksheet.WorksheetPart.TableDefinitionParts.FirstOrDefault<TableDefinitionPart>();

                // Total
                OpenXML.SetCellValue(spreadsheet, worksheet, 8, 2, CellValues.String, "Total Documento", _totalHeaderStyle, true);
                OpenXML.SetCellFormula(spreadsheet, worksheet, 9, 2, "=SUM(C4:C1048576)", 2, true);

                OpenXML.SetCellValue(spreadsheet, worksheet, 8, 3, CellValues.String, "Total Pendente", _totalHeaderStyle, true);
                OpenXML.SetCellFormula(spreadsheet, worksheet, 9, 3, "=SUM(D4:D1048576)", 2, true);

                // Last Sync
                var lastSync = DateTime.Now;
                OpenXML.SetCellValue(spreadsheet, worksheet, 8, 1, CellValues.String, "Última Sincronização", _totalHeaderStyle, true);
                OpenXML.SetCellValue(spreadsheet, worksheet, 9, 1, lastSync, _dateStyle, true);

                // Set column widths
                OpenXML.SetColumnWidth(worksheet, 1, 22);
                OpenXML.SetColumnWidth(worksheet, 2, 22);
                OpenXML.SetColumnWidth(worksheet, 3, 22);
                OpenXML.SetColumnWidth(worksheet, 4, 22);
                OpenXML.SetColumnWidth(worksheet, 5, 22);
                OpenXML.SetColumnWidth(worksheet, 6, 22);

                OpenXML.SetColumnWidth(worksheet, 8, 22);
                OpenXML.SetColumnWidth(worksheet, 9, 22);

                worksheet.Save();
                spreadsheet.Close();

                return ms.ToArray();
            }
        }
    }
}

CreateTable方法

public static void CreateTable(SpreadsheetDocument document, Worksheet worksheet, string TableName, uint rowStart, uint columnStart, uint rowEnd, uint columnEnd)
    {
        string cellAddressStart = ColumnNameFromIndex(columnStart) + rowStart;
        string cellAddressEnd = ColumnNameFromIndex(columnEnd) + rowEnd;
        string tableAddress = cellAddressStart + ":" + cellAddressEnd;

        TableDefinitionPart tableDefinitionPart1 = worksheet.WorksheetPart.AddNewPart<TableDefinitionPart>("rId1");

        Table table1 = new Table() { Id = (UInt32Value)2U, Name = TableName, DisplayName = TableName, Reference = tableAddress, TotalsRowShown = false };
        AutoFilter autoFilter1 = new AutoFilter() { Reference = tableAddress };

        uint cellRangeCount = columnEnd - columnStart;
        TableColumns tableColumns1 = new TableColumns() { Count = (UInt32Value)(cellRangeCount) };
        uint cellCount = 1;
        for (uint idxColumns = columnStart; idxColumns < columnEnd; idxColumns++)
        {
            CellValue cell = GetCellValue(document, worksheet, idxColumns, rowStart);
            TableColumn tableColumn1 = new TableColumn() { Id = (UInt32Value)cellCount, Name = cell.InnerText };
            tableColumns1.Append(tableColumn1);
            cellCount++;
        }

        TableStyleInfo tableStyleInfo1 = new TableStyleInfo() { Name = "TableStyleMedium2", 
                                                                ShowFirstColumn = false, 
                                                                ShowLastColumn = false, 
                                                                ShowRowStripes = true, 
                                                                ShowColumnStripes = false };

        table1.Append(autoFilter1);
        table1.Append(tableColumns1);
        table1.Append(tableStyleInfo1);

        tableDefinitionPart1.Table = table1;
    }

我正在使用

添加单元格（行）

var currentAccountData = GetData();

uint rowIdx = 4;
foreach (var item in currentAccountData)
{
    OpenXML.SetCellValue(spreadsheet, worksheet, 1, rowIdx, CellValues.String, item.TypeDoc, _generalStyle, true);
    OpenXML.SetCellValue(spreadsheet, worksheet, 2, rowIdx, CellValues.String, item.NrDoc, _generalStyle, true);
    if (item.DocValue != null)
        OpenXML.SetCellValue(spreadsheet, worksheet, 3, rowIdx, Convert.ToDouble(item.DocValue), _currencyStyle, true);
    if (item.PendingValue != null)
        OpenXML.SetCellValue(spreadsheet, worksheet, 4, rowIdx, Convert.ToDouble(item.PendingValue), _currencyStyle, true);
    if (item.RecordDate != null)
        OpenXML.SetCellValue(spreadsheet, worksheet, 5, rowIdx, item.RecordDate, _dateStyle, true);
    if (item.SalaryDate != null)
        OpenXML.SetCellValue(spreadsheet, worksheet, 6, rowIdx, item.SalaryDate, _dateStyle, true);

    rowIdx++;
}

然后创建tablepart

TableParts tableParts1 = new TableParts() { Count = (uint)1U };
TablePart tablePart1 = new TablePart() { Id = "rId1" };
tableParts1.Append(tablePart1);
worksheet.Append(tableParts1);

之后，我使用方法OpenXML.CreateTable

OpenXML.CreateTable(spreadsheet, worksheet, "table1", 3U, 1U, (uint)currentAccountData.Count + 3, 6U);

我做错了什么？

如果您需要更多代码，我将上传该应用程序。谢谢。

编辑：

当我打开excel时，它说：

删除了部分：/xl/tables/table.xml部分，带有XML错误。（表）A 文档必须只包含一个根元素。第1行，第0列。

我做错了什么？

你的调试方法对我来说似乎不对。我建议以下之一：

一个。将生成的xml与手工制作的xlsx文件进行比较。
湾从代码开始，由OpenXML生产力工具生成（所以它在您的应用程序中生成静态表）并修改/重新计算它一步一步地使用您的应用程序中的动态数据并符合您的编码标准 - 这样您就可以发现您的其中一个迭代的错误或只是得到一个干净的工作解决方案

OpenXML动态创建“表/数据透视表”
