c# – 使用OpenXML将％数字格式应用于单元格值

WorkbookStylesPart sp = workbookPart.AddNewPart<WorkbookStylesPart>();

创建样式表,

sp.Stylesheet = new Stylesheet();

创建一个编号格式,

sp.Stylesheet.NumberingFormats = new NumberingFormats();
// #.##% is also Excel style index 1

NumberingFormat nf2decimal = new NumberingFormat();
nf2decimal.NumberFormatId = UInt32Value.FromUInt32(3453);
nf2decimal.FormatCode = StringValue.FromString("0.0%");
sp.Stylesheet.NumberingFormat.Append(nf2decimal);

创建单元格格式并应用编号格式ID

cellFormat = new CellFormat();
cellFormat.FontId = 0;
cellFormat.FillId = 0;
cellFormat.BorderId = 0;
cellFormat.FormatId = 0;
cellFormat.NumberFormatId = nf2decimal.NumberFormatId;
cellFormat.ApplyNumberFormat = BooleanValue.FromBoolean(true);
cellFormat.ApplyFont = true;

//append cell format for cells of header row
sp.Stylesheet.CellFormats.AppendChild<CellFormat>(cellFormat);


//update font count 
sp.Stylesheet.CellFormats.Count = UInt32Value.FromUInt32((uint)sp.Stylesheet.CellFormats.ChildElements.Count);


//save the changes to the style sheet part   
sp.Stylesheet.Save();

当您将值附加到单元格时,具有以下中心代码hereonversion并应用样式索引
在我的情况下我有三个样式索引,因此3个是我的百分比样式索引,即索引从0开始的2

string val = Convert.ToString(Convert.ToDecimal(value)/100);
Cell cell = new Cell();
cell.DataType = new EnumValue<CellValues>(CellValues.Number);
cell.CellValue = new CellValue(val);
cell.StyleIndex = 2;
row.Append(cell);
