使用的OpenXML

Question

请考虑这个Excel中创建合并单元格：

，它的XML：

我想创建这样这个Excel有使用OpenXML的多个单元格合并。

我该怎么做？

感谢

您可以使用MergeCells和MergeCell类来创建你需要合并单元格。 MergeCells类是合并单元的集合（XML中的<mergeCells count="3">），而MergeCell类表示合并单元的每个单独集合（XML中的<mergeCell ref="xx:xx" />）。要在合并单元格中填充数据，您需要将值添加到最左上角的单元格;任何其他值将被忽略。

以下代码将创建一个合并单元格的新文件。

using (SpreadsheetDocument myDoc = SpreadsheetDocument.Create(filename, SpreadsheetDocumentType.Workbook)) 
{ 
    WorkbookPart workbookpart = myDoc.AddWorkbookPart(); 
    workbookpart.Workbook = new Workbook(); 

    // Add a WorksheetPart to the WorkbookPart. 
    WorksheetPart worksheetPart = workbookpart.AddNewPart<WorksheetPart>(); 

    SheetData sheetData = new SheetData(); 

    //add a row 
    Row firstRow = new Row(); 
    firstRow.RowIndex = (UInt32)1; 

    //create a cell in C1 (the upper left most cell of the merged cells) 
    Cell dataCell = new Cell(); 
    dataCell.CellReference = "C1"; 
    CellValue cellValue = new CellValue(); 
    cellValue.Text = "99999"; 
    dataCell.Append(cellValue); 

    firstRow.AppendChild(dataCell); 

    sheetData.AppendChild(firstRow); 
    // Add a WorkbookPart to the document. 
    worksheetPart.Worksheet = new Worksheet(sheetData); 

    //create a MergeCells class to hold each MergeCell 
    MergeCells mergeCells = new MergeCells(); 

    //append a MergeCell to the mergeCells for each set of merged cells 
    mergeCells.Append(new MergeCell() { Reference = new StringValue("C1:F1") }); 
    mergeCells.Append(new MergeCell() { Reference = new StringValue("A3:B3") }); 
    mergeCells.Append(new MergeCell() { Reference = new StringValue("G5:K5") }); 

    worksheetPart.Worksheet.InsertAfter(mergeCells, worksheetPart.Worksheet.Elements<SheetData>().First()); 

    //this is the part that was missing from your code 
    Sheets sheets = myDoc.WorkbookPart.Workbook.AppendChild(new Sheets()); 
    sheets.AppendChild(new Sheet() 
    { 
     Id = myDoc.WorkbookPart.GetIdOfPart(myDoc.WorkbookPart.WorksheetParts.First()), 
     SheetId = 1, 
     Name = "Sheet1" 
    }); 
}
