OpenXML sdk 2.5 Excel 新列问题

Question

我有一部分代码使用 OpenXML 生成 Excel 文档。问题是设置自定义列宽。这个问题经常被问到在此讨论了 SO，但不幸的是对我没有任何帮助。

所以这里是创建文件的代码：

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

创建后我尝试将自定义列宽设置为第一列

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();

代码运行无任何异常，但结果文件已损坏这是结构 opf 结果 sheet xml

<?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？

更新。问题已解决，感谢 petelids。我刚刚添加：

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

然后，这里只指定范围Min = (UInt32Value)5U, Max = (UInt32Value)5U

您的元素顺序不正确，导致文件损坏消息。 ECMA-376 standard 将 Worksheet 的 XML 定义为

<xsd:complexType name="CT_Worksheet">
  <xsd:sequence>
    <xsd:element name="sheetPr" type="CT_SheetPr" minOccurs="0" maxOccurs="1"/>

    <xsd:element name="ignoredErrors" type="CT_IgnoredErrors" minOccurs="0" maxOccurs="1"/>
    <xsd:element name="smartTags" type="CT_SmartTags" minOccurs="0" maxOccurs="1"/>
    <xsd:element name="drawing" type="CT_Drawing" minOccurs="0" maxOccurs="1"/>
    <xsd:element name="drawingHF" type="CT_DrawingHF" minOccurs="0" maxOccurs="1"/>
    <xsd:element name="picture" type="CT_SheetBackgroundPicture" minOccurs="0" maxOccurs="1"/>
    <xsd:element name="oleObjects" type="CT_OleObjects" minOccurs="0" maxOccurs="1"/>
    <xsd:element name="controls" type="CT_Controls" minOccurs="0" maxOccurs="1"/>
    <xsd:element name="webPublishItems" type="CT_WebPublishItems" minOccurs="0" maxOccurs="1"/>

    <xsd:element name="extLst" type="CT_ExtensionList" minOccurs="0" maxOccurs="1"/>
  </xsd:sequence>
</xsd:complexType>

请注意，它是一个 sequence，因此项目的顺序很重要，cols 在 sheetData 之前（第 5 和 6 行）。

在您的情况下，您需要在 SheetData 之前直接添加 Columns。 Worksheet 上有一个 InsertBefore 方法，可用于代替您对 Append.
