OpenXML中小号preadsheet单元格样式（S preadsheetML） [英] Cell styles in OpenXML spreadsheet (SpreadsheetML)

问题描述

我已经生成使用的OpenXML的SDK C＃中的.xlsx US preadsheet，但无法弄清楚如何让单元格样式的工作。我一直在学习用Excel制作的文件，并不能完全弄清楚它是如何做。

I've generated a .xlsx spreadsheet in C# using the OpenXML SDK, but can't figure out how to get cell styles working. I've been studying files produced by Excel, and can't quite figure out how it's done.

现在，我创建一个填充，创建一个 CellStyleFormat ，在填充点，创造了 CellFormat 指向指数在 CellStyleFormat ，然后创建一个 CellStyle 是指向 CellFormat 。

Right now, I'm creating a fill, creating a CellStyleFormat that points at the fill, creating a CellFormat that points at the index of the CellStyleFormat, then creating a CellStyle that points to the CellFormat.

这里的code我使用生成文件：

Here's the code I'm using to generate the document:

Console.WriteLine("Creating document");
using (var spreadsheet = SpreadsheetDocument.Create("output.xlsx", SpreadsheetDocumentType.Workbook))
{
    Console.WriteLine("Creating workbook");
    spreadsheet.AddWorkbookPart();
    spreadsheet.WorkbookPart.Workbook = new Workbook();
    Console.WriteLine("Creating worksheet");
    var wsPart = spreadsheet.WorkbookPart.AddNewPart<WorksheetPart>();
    wsPart.Worksheet = new Worksheet();

    var stylesPart = spreadsheet.WorkbookPart.AddNewPart<WorkbookStylesPart>();
    stylesPart.Stylesheet = new Stylesheet();
    stylesPart.Stylesheet.Fills = new Fills();

    // create a solid red fill
    var solidRed = new PatternFill() { PatternType = PatternValues.Solid };
    solidRed.AppendChild(new BackgroundColor { Rgb = HexBinaryValue.FromString("FF00FF00") });

    stylesPart.Stylesheet.Fills.AppendChild(new Fill { PatternFill = new PatternFill() { PatternType = PatternValues.None } });
    stylesPart.Stylesheet.Fills.AppendChild(new Fill { PatternFill = solidRed });
    stylesPart.Stylesheet.CellStyleFormats = new CellStyleFormats();
    stylesPart.Stylesheet.CellStyleFormats.AppendChild(new CellFormat { FillId = 0, ApplyFill = false });
    stylesPart.Stylesheet.CellStyleFormats.AppendChild(new CellFormat { FillId = 1, ApplyFill = true });
    stylesPart.Stylesheet.CellFormats = new CellFormats();
    stylesPart.Stylesheet.CellFormats.AppendChild(new CellFormat { FormatId = 0 });
    stylesPart.Stylesheet.CellFormats.AppendChild(new CellFormat { FormatId = 1 });
    stylesPart.Stylesheet.CellStyles = new CellStyles();
    stylesPart.Stylesheet.CellStyles.AppendChild(new CellStyle { Name = "None", FormatId = 0 });
    stylesPart.Stylesheet.CellStyles.AppendChild(new CellStyle { Name = "Solid Red", FormatId = 1 });

    stylesPart.Stylesheet.Save();

    Console.WriteLine("Creating sheet data");
    var sheetData = wsPart.Worksheet.AppendChild(new SheetData());

    Console.WriteLine("Adding rows / cells...");

    var row = sheetData.AppendChild(new Row());
    row.AppendChild(new Cell() { CellValue = new CellValue("This"),  DataType = CellValues.String });
    row.AppendChild(new Cell() { CellValue = new CellValue("is"),    DataType = CellValues.String });
    row.AppendChild(new Cell() { CellValue = new CellValue("a"),     DataType = CellValues.String });
    row.AppendChild(new Cell() { CellValue = new CellValue("test."), DataType = CellValues.String });

    sheetData.AppendChild(new Row());

    row = sheetData.AppendChild(new Row());
    row.AppendChild(new Cell() { CellValue = new CellValue("Value:"),   DataType = CellValues.String });
    row.AppendChild(new Cell() { CellValue = new CellValue("123"),      DataType = CellValues.Number });
    row.AppendChild(new Cell() { CellValue = new CellValue("Formula:"), DataType = CellValues.String });
    row.AppendChild(new Cell() { CellFormula = new CellFormula("B3"),   StyleIndex = 1 }); // 

    Console.WriteLine("Saving worksheet");
    wsPart.Worksheet.Save();

    Console.WriteLine("Creating sheet list");
    var sheets = spreadsheet.WorkbookPart.Workbook.AppendChild(new Sheets());
    sheets.AppendChild(new Sheet() { Id = spreadsheet.WorkbookPart.GetIdOfPart(wsPart), SheetId = 1, Name = "Test" });

    Console.WriteLine("Saving workbook");
    spreadsheet.WorkbookPart.Workbook.Save();

    Console.WriteLine("Done.");
}

下面是生成的XML：

workbook.xml

<?xml version="1.0" encoding="utf-8"?>
<x:workbook xmlns:x="http://schemas.openxmlformats.org/spreadsheetml/2006/main">
  <x:sheets>
    <x:sheet name="Test" sheetId="1" r:id="Rbad86b8c80844a16" xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships" />
  </x:sheets>
</x:workbook>

styles.xml

<?xml version="1.0" encoding="utf-8"?>
<x:styleSheet xmlns:x="http://schemas.openxmlformats.org/spreadsheetml/2006/main">
  <x:fills>
    <x:fill>
      <x:patternFill patternType="none" />
    </x:fill>
    <x:fill>
      <x:patternFill patternType="solid">
        <x:bgColor rgb="FF00FF00" />
      </x:patternFill>
    </x:fill>
  </x:fills>
  <x:cellStyleXfs>
    <x:xf fillId="0" applyFill="0" />
    <x:xf fillId="1" applyFill="1" />
  </x:cellStyleXfs>
  <x:cellXfs>
    <x:xf xfId="0" />
    <x:xf xfId="1" />
  </x:cellXfs>
  <x:cellStyles>
    <x:cellStyle name="None" xfId="0" />
    <x:cellStyle name="Solid Red" xfId="1" />
  </x:cellStyles>
</x:styleSheet>

工作表/ sheet.xml

<?xml version="1.0" encoding="utf-8"?>
<x:worksheet xmlns:x="http://schemas.openxmlformats.org/spreadsheetml/2006/main">
  <x:sheetData>
    <x:row>
      <x:c t="str"><x:v>This</x:v></x:c>
      <x:c t="str"><x:v>is</x:v></x:c>
      <x:c t="str"><x:v>a</x:v></x:c>
      <x:c t="str"><x:v>test.</x:v></x:c>
    </x:row>
    <x:row />
    <x:row>
      <x:c t="str"><x:v>Value:</x:v></x:c>
      <x:c t="n"><x:v>123</x:v></x:c>
      <x:c t="str"><x:v>Formula:</x:v></x:c>
      <x:c s="1"><x:f>B3</x:f></x:c>
    </x:row>
  </x:sheetData>
</x:worksheet>

最后一行的最后一个单元格就是我想要添加的风格。

The last cell of the last row is where I'm trying to add the style.

这一切正确地验证当我运行它通过OpenXML的SDK生产力工具，但是，当我尝试在Excel中打开该文件，我得到以下错误：

This all validates properly when I run it through the OpenXML SDK Productivity Tool, but, when I attempt to open the file in Excel, I get the following error:

修复记录：从/xl/styles.xml部分格式（样式）

Repaired Records: Format from /xl/styles.xml part (Styles)

在S preadsheet然后显示，但不应用填充。

The spreadsheet then shows, but the fill isn't applied.

不知道如何去解决这个？

Any idea how to go about fixing this?

推荐答案

好吧，我设法弄清楚这一点，很多实验后。

Right, I managed to figure this out, after a lot of experimentation.

原来，Excel分别将其保留风格0和1的正常细胞和Gray125图案填充。上述大部分code可以去掉，因为我们只需要一个 CellFormat 真的。

It turns out that excel reserves styles 0 and 1 for normal cells and "Gray125" pattern fill respectively. Most of the above code can be removed, as we only need a CellFormat really.

工作code：

Console.WriteLine("Creating document");
using (var spreadsheet = SpreadsheetDocument.Create("output.xlsx", SpreadsheetDocumentType.Workbook))
{
    Console.WriteLine("Creating workbook");
    spreadsheet.AddWorkbookPart();
    spreadsheet.WorkbookPart.Workbook = new Workbook();
    Console.WriteLine("Creating worksheet");
    var wsPart = spreadsheet.WorkbookPart.AddNewPart<WorksheetPart>();
    wsPart.Worksheet = new Worksheet();

    var stylesPart = spreadsheet.WorkbookPart.AddNewPart<WorkbookStylesPart>();
    stylesPart.Stylesheet = new Stylesheet();

    Console.WriteLine("Creating styles");

    // blank font list
    stylesPart.Stylesheet.Fonts = new Fonts();
    stylesPart.Stylesheet.Fonts.Count = 1;
    stylesPart.Stylesheet.Fonts.AppendChild(new Font());

    // create fills
    stylesPart.Stylesheet.Fills = new Fills();

    // create a solid red fill
    var solidRed = new PatternFill() { PatternType = PatternValues.Solid };
    solidRed.ForegroundColor = new ForegroundColor { Rgb = HexBinaryValue.FromString("FFFF0000") }; // red fill
    solidRed.BackgroundColor = new BackgroundColor { Indexed = 64 };

    stylesPart.Stylesheet.Fills.AppendChild(new Fill { PatternFill = new PatternFill { PatternType = PatternValues.None } }); // required, reserved by Excel
    stylesPart.Stylesheet.Fills.AppendChild(new Fill { PatternFill = new PatternFill { PatternType = PatternValues.Gray125 } }); // required, reserved by Excel
    stylesPart.Stylesheet.Fills.AppendChild(new Fill { PatternFill = solidRed });
    stylesPart.Stylesheet.Fills.Count = 3;

    // blank border list
    stylesPart.Stylesheet.Borders = new Borders();
    stylesPart.Stylesheet.Borders.Count = 1;
    stylesPart.Stylesheet.Borders.AppendChild(new Border());

    // blank cell format list
    stylesPart.Stylesheet.CellStyleFormats = new CellStyleFormats();
    stylesPart.Stylesheet.CellStyleFormats.Count = 1;
    stylesPart.Stylesheet.CellStyleFormats.AppendChild(new CellFormat());

    // cell format list
    stylesPart.Stylesheet.CellFormats = new CellFormats();
    // empty one for index 0, seems to be required
    stylesPart.Stylesheet.CellFormats.AppendChild(new CellFormat());
    // cell format references style format 0, font 0, border 0, fill 2 and applies the fill
    stylesPart.Stylesheet.CellFormats.AppendChild(new CellFormat { FormatId = 0, FontId = 0, BorderId = 0, FillId = 2, ApplyFill = true }).AppendChild(new Alignment { Horizontal = HorizontalAlignmentValues.Center });
    stylesPart.Stylesheet.CellFormats.Count = 2;

    stylesPart.Stylesheet.Save();

    Console.WriteLine("Creating sheet data");
    var sheetData = wsPart.Worksheet.AppendChild(new SheetData());

    Console.WriteLine("Adding rows / cells...");

    var row = sheetData.AppendChild(new Row());
    row.AppendChild(new Cell() { CellValue = new CellValue("This"),  DataType = CellValues.String });
    row.AppendChild(new Cell() { CellValue = new CellValue("is"),    DataType = CellValues.String });
    row.AppendChild(new Cell() { CellValue = new CellValue("a"),     DataType = CellValues.String });
    row.AppendChild(new Cell() { CellValue = new CellValue("test."), DataType = CellValues.String });

    sheetData.AppendChild(new Row());

    row = sheetData.AppendChild(new Row());
    row.AppendChild(new Cell() { CellValue = new CellValue("Value:"),   DataType = CellValues.String });
    row.AppendChild(new Cell() { CellValue = new CellValue("123"),      DataType = CellValues.Number });
    row.AppendChild(new Cell() { CellValue = new CellValue("Formula:"), DataType = CellValues.String });
    // style index = 1, i.e. point at our fill format
    row.AppendChild(new Cell() { CellFormula = new CellFormula("B3"),   DataType = CellValues.Number, StyleIndex = 1 });

    Console.WriteLine("Saving worksheet");
    wsPart.Worksheet.Save();

    Console.WriteLine("Creating sheet list");
    var sheets = spreadsheet.WorkbookPart.Workbook.AppendChild(new Sheets());
    sheets.AppendChild(new Sheet() { Id = spreadsheet.WorkbookPart.GetIdOfPart(wsPart), SheetId = 1, Name = "Test" });

    Console.WriteLine("Saving workbook");
    spreadsheet.WorkbookPart.Workbook.Save();

    Console.WriteLine("Done.");
}
