c# – 使用OpenXml sdk 2.0创建Excel文档

我已经使用OpenXml SDK 2.0创建了一个Excel文档,现在我必须对它进行风格化,但是我不能。

我不知道如何绘制背景颜色或更改不同单元格中的字体大小。

我的代码创建一个单元格是:

private static Cell CreateTextCell(string header, string text, UInt32Value index)
{
    Cell c = new Cell();
    c.DataType = CellValues.InlineString;
    c.CellReference = header + index;
    InlineString inlineString = new InlineString();
    DocumentFormat.OpenXml.Spreadsheet.Text t = new DocumentFormat.OpenXml.Spreadsheet.Text();
    t.Text = text;
    inlineString.AppendChild(t);
    c.AppendChild(inlineString);
    return c;
} 
注意:OpenXML 2.0 SDK目前在CTP中,直到Office2010才能获得生产许可。

处理OpenXML SDK的一般方法是创建一个空白文档和一个文档,只需要了解如何实现(如背景颜色)的功能,并使用SDK的OpenXmlDiff来查看需要实现的更改的功能。

如果从头开始创建文档,则可以使用DocumentReflector生成默认Stylesheet对象的代码,然后添加所需的样式。

从默认开始:

new Stylesheet(
new Fonts(
    new Font(
        new FontSize() { Val = 10D },
        new Color() { Theme = (UInt32Value)1U },
        new FontName() { Val = "Arial" },
        new FontFamilyNumbering() { Val = 2 })
) { Count = (UInt32Value)1U },
new Fills(
    new Fill(
        new PatternFill() { PatternType = PatternValues.None }),
    new Fill(
        new PatternFill() { PatternType = PatternValues.Gray125 })
) { Count = (UInt32Value)2U },
new Borders(...
...
...
new CellFormats(
new CellFormat() { NumberFormatId = (UInt32Value)0U, FontId = (UInt32Value)0U, FillId = (UInt32Value)0U, BorderId = (UInt32Value)0U, FormatId = (UInt32Value)0U }) { Count = (UInt32Value)1U }, ...

我添加了一个大小为12的新字体和一个带有红色背景的新填充(Indexed值为64),并添加了引用新Font和Fill的索引的新CellFormats。 (确保更新计数)

new Stylesheet(
    new Fonts(
        new Font(
            new FontSize() { Val = 10D },
            new Color() { Theme = (UInt32Value)1U },
            new FontName() { Val = "Arial" },
            new FontFamilyNumbering() { Val = 2 }),
        new Font(
            new FontSize() { Val = 12D },
            new Color() { Theme = (UInt32Value)1U },
            new FontName() { Val = "Arial" },
            new FontFamilyNumbering() { Val = 2 })
            ) { Count = (UInt32Value)2U },
    new Fills(
        new Fill(
            new PatternFill() { PatternType = PatternValues.None }),
        new Fill(
            new PatternFill() { PatternType = PatternValues.Gray125 }),
        new Fill(
            new PatternFill() { PatternType = PatternValues.Solid, ForegroundColor = new ForegroundColor() { Rgb = "FFFF0000" }, BackgroundColor = new BackgroundColor() { Indexed = 64 } })
            ) { Count = (UInt32Value)3U },
    new Borders(
        new Border(
            new LeftBorder(), new RightBorder(), new TopBorder(), new BottomBorder(), new DiagonalBorder())
    ) { Count = (UInt32Value)1U },
    new CellStyleFormats(
        new CellFormat() { NumberFormatId = (UInt32Value)0U, FontId = (UInt32Value)0U, FillId = (UInt32Value)0U, BorderId = (UInt32Value)0U }
    ) { Count = (UInt32Value)1U },
    new CellFormats(
        new CellFormat() { NumberFormatId = (UInt32Value)0U, FontId = (UInt32Value)0U, FillId = (UInt32Value)0U, BorderId = (UInt32Value)0U, FormatId = (UInt32Value)0U },
        new CellFormat() { NumberFormatId = (UInt32Value)0U, FontId = (UInt32Value)1U, FillId = (UInt32Value)0U, BorderId = (UInt32Value)0U, FormatId = (UInt32Value)0U },
        new CellFormat() { NumberFormatId = (UInt32Value)0U, FontId = (UInt32Value)0U, FillId = (UInt32Value)2U, BorderId = (UInt32Value)0U, FormatId = (UInt32Value)0U }
    ) { Count = (UInt32Value)3U },
    new CellStyles(
        new CellStyle() { Name = "Normal", FormatId = (UInt32Value)0U, BuiltinId = (UInt32Value)0U }
    ) { Count = (UInt32Value)1U },
    new DifferentialFormats() { Count = (UInt32Value)0U },
    new TableStyles() { Count = (UInt32Value)0U, DefaultTableStyle = "TableStyleMedium9", DefaultPivotStyle = "PivotStyleLight16" });

然后,在代码中,我将CellStyle索引应用于要格式化的单元格:
(单元格A2和A3中已有数据,单元格A2的尺寸越大,A3的红色背景)

SheetData sheetData = worksheetPart.Worksheet.GetFirstChild<SheetData>();
sheetData.Descendants<Row>().Where(r => r.RowIndex == 2U).First().Descendants<Cell>().First().StyleIndex = 1U;
sheetData.Descendants<Row>().Where(r => r.RowIndex == 3U).First().Descendants<Cell>().First().StyleIndex = 2U;
