OpenXML编写器列

我有一个问题要问使用OpenXMLWriter。

我目前使用下面的代码来创build我的Excel文件，但我想设置列的宽度。 我应该怎么做？

因为我试图在Worksheet（）和SheetData（）之间写新列，到目前为止我还没有成功。

例子会非常有帮助。 感谢它，谢谢！

using (SpreadsheetDocument xl = SpreadsheetDocument.Create("LargeFile.xlsx", SpreadsheetDocumentType.Workbook)) { List<OpenXmlAttribute> oxa; OpenXmlWriter oxw; xl.AddWorkbookPart(); WorksheetPart wsp = xl.WorkbookPart.AddNewPart<WorksheetPart>(); oxw = OpenXmlWriter.Create(wsp); oxw.WriteStartElement(new Worksheet()); oxw.WriteStartElement(new SheetData()); for (int i = 1; i <= 50000; ++i) { oxa = new List<OpenXmlAttribute>(); // this is the row index oxa.Add(new OpenXmlAttribute("r", null, i.ToString())); oxw.WriteStartElement(new Row(), oxa); for (int j = 1; j <= 100; ++j) { oxa = new List<OpenXmlAttribute>(); // this is the data type ("t"), with CellValues.String ("str") oxa.Add(new OpenXmlAttribute("t", null, "str")); // it's suggested you also have the cell reference, but // you'll have to calculate the correct cell reference yourself. // Here's an example: //oxa.Add(new OpenXmlAttribute("r", null, "A1")); oxw.WriteStartElement(new Cell(), oxa); oxw.WriteElement(new CellValue(string.Format("R{0}C{1}", i, j))); // this is for Cell oxw.WriteEndElement(); } // this is for Row oxw.WriteEndElement(); }

在这些代码行之间：

 oxw.WriteStartElement(new Worksheet()); oxw.WriteStartElement(new SheetData()); 

添加额外的代码部分：

 oxw.WriteStartElement(new Worksheet()); oxw.WriteStartElement(new Columns()); oxa = new List<OpenXmlAttribute>(); // min and max are required attributes // This means from columns 2 to 4, both inclusive oxa.Add(new OpenXmlAttribute("min", null, "2")); oxa.Add(new OpenXmlAttribute("max", null, "4")); oxa.Add(new OpenXmlAttribute("width", null, "25")); oxw.WriteStartElement(new Column(), oxa); oxw.WriteEndElement(); oxa = new List<OpenXmlAttribute>(); oxa.Add(new OpenXmlAttribute("min", null, "6")); oxa.Add(new OpenXmlAttribute("max", null, "6")); oxa.Add(new OpenXmlAttribute("width", null, "40")); oxw.WriteStartElement(new Column(), oxa); oxw.WriteEndElement(); oxw.WriteEndElement(); oxw.WriteStartElement(new SheetData());

简单的方法是使用excel模板，并根据您的需要更改宽度。 稍后当您写入数据时，列宽将自动保留。

另一种方法是：使用OpenXML生产力工具反映您所需的Excel文件的代码。 然后使用文件中的样式信息以编程方式设置单元格/列的宽度。
