ExcelSDK2.5Excel新列问题

Question

我有一部分代码使用OpenXML生成Excel文档。问题是如何设置自定义列宽度。这个问题经常在这里讨论，但不幸的是，对我没有任何帮助。

在这里，创建文件的代码：

SpreadsheetDocument spreadsheetDocument = SpreadsheetDocument.Create(stream
     , SpreadsheetDocumentType.Workbook);
WorkbookPart workbookpart = spreadsheetDocument.AddWorkbookPart();
workbookpart.Workbook = new Workbook();
WorksheetPart worksheetPart = workbookpart.AddNewPart<WorksheetPart>();
worksheetPart.Worksheet = new Worksheet(new SheetData());
Sheets sheets = spreadsheetDocument.WorkbookPart.Workbook.
AppendChild<Sheets>(new Sheets());
Sheet sheet = new Sheet()
{
     Id = spreadsheetDocument.WorkbookPart.
     GetIdOfPart(worksheetPart),
     SheetId = 1,
     Name = _sheetName
};
sheets.Append(sheet);
document = spreadsheetDocument;
wbPart = workbookpart

创建后，我将尝试将自定义列宽度设置为第一列。

Worksheet ws = ((WorksheetPart)(wbPart.GetPartById(sheet.Id))).Worksheet;
Columns columns = new Columns();                
Column column = new Column() { Min = (UInt32Value)5U, Max = (UInt32Value)5U,
     Width = 16D, CustomWidth = true };
columns.Append(column);
ws.Append(columns);
ws.Save();

代码运行时没有任何异常，但是结果文件被破坏了--这里是opf结果表xml结构。

<?xml version="1.0" encoding="UTF-8"?>
-<x:worksheet xmlns:x="http://schemas.openxmlformats.org/spreadsheetml/2006/main">
-<x:sheetData> 
      -<x:row r="7"> 
         -<x:c r="A7" t="s" s="6">    
              <x:v>11</x:v>   
          </x:c> 
         -<x:c r="B7" t="s" s="6">    
              <x:v>12</x:v>    
          </x:c>  
         -<x:c r="C7" t="s" s="6">    
              <x:v>13</x:v>    
          </x:c>    
     </x:row>    
</x:sheetData>
-<x:cols>    
     <x:col customWidth="1" width="16" max="5" min="5"/>    
</x:cols>    
</x:worksheet>

，所以问题是，我做错了什么?

UPD。问题解决了，多亏了节肢动物。我刚才补充说：

SheetData sheetData = ws.GetFirstChild<SheetData>();
ws.InsertBefore(columns,sheetData);

然后，只在这里指定Min = (UInt32Value)5U，Max = (UInt32Value)5U的范围

您的元素顺序不正确，这会导致文件消息损坏。ECMA-376标准将Worksheet的XML定义为

</xsd:complexType>

注意，它是一个sequence，所以条目的顺序和cols位于sheetData之前(第5和第6行)。

在您的示例中，需要将Columns直接添加到SheetData之前。在InsertBefore上有一个Worksheet方法，可以用来代替对Append的调用。
