如何为特定的行着色

Question

我是第一次开始使用SpreadsheetLight将数据表导出到excel。我的目标是设置特定的行颜色。我尝试过，但是没有颜色。对我来说，问题还不清楚，我在哪里犯了代码错误。请查看我的代码，并告诉我我想在代码中添加的内容。

我为颜色创建了自定义主题。

using DocumentFormat.OpenXml;
using DocumentFormat.OpenXml.Spreadsheet;
using SpreadsheetLight;

private SLThemeSettings BuildTheme()
{
    SLThemeSettings theme = new SLThemeSettings();
    theme.ThemeName = "RDSColourTheme";
    //theme.MajorLatinFont = "Impact";
    //theme.MinorLatinFont = "Harrington";
    // this is recommended to be pure white
    theme.Light1Color = System.Drawing.Color.White;
    // this is recommended to be pure black
    theme.Dark1Color = System.Drawing.Color.Black;
    theme.Light2Color = System.Drawing.Color.Gray;
    theme.Dark2Color = System.Drawing.Color.IndianRed;
    theme.Accent1Color = System.Drawing.Color.Red;
    theme.Accent2Color = System.Drawing.Color.Tomato;
    theme.Accent3Color = System.Drawing.Color.Yellow;
    theme.Accent4Color = System.Drawing.Color.LawnGreen;
    theme.Accent5Color = System.Drawing.Color.DeepSkyBlue;
    theme.Accent6Color = System.Drawing.Color.DarkViolet;
    theme.Hyperlink = System.Drawing.Color.Blue;
    theme.FollowedHyperlinkColor = System.Drawing.Color.Purple;
    return theme;
}

private void button1_Click(object sender, EventArgs e)
{
    Random rand = new Random();

    System.Data.DataTable dt = new System.Data.DataTable();
    dt.Columns.Add("Product", typeof(string));
    dt.Columns.Add("IP Address", typeof(string));
    dt.Columns.Add("Date (UTC)", typeof(DateTime));
    dt.Columns.Add("Size (MB)", typeof(double));
    dt.Columns.Add("Cost", typeof(decimal));

    for (int i = 0; i < 10; ++i)
    {
    dt.Rows.Add(string.Format("Prod{0}", i+1),
        string.Format("{0}.{1}.{2}.{3}", rand.Next(256), rand.Next(256), rand.Next(256), rand.Next(256)),
        DateTime.UtcNow.AddDays(rand.NextDouble() * 20),
        decimal.Round((decimal)(rand.NextDouble() * 500 + 200), 4),
        decimal.Round((decimal)(rand.NextDouble() * 20 + 5), 2));
    }

    //SLThemeSettings stSettings = BuildTheme();
    SLDocument sl = new SLDocument();
    sl.ImportDataTable(1, 1, dt, true);

    // This part sets the style, but you might be using a template file,
    // so the styles are probably already set.

    ////setting date format for column 4
    SLStyle style = sl.CreateStyle();
    style.FormatCode = "MM/dd/yyyy";
    sl.SetColumnStyle(3, style);

    //fixed first row and 3 columns from left
    sl.FreezePanes(1, 4);


    //// setting first row color & style
    SLStyle headerstyle = sl.CreateStyle();
    headerstyle.Font.Bold = true;
    //headerstyle.Fill.SetPatternBackgroundColor(PatternValues.Solid, System.Drawing.Color.IndianRed, System.Drawing.Color.Gray);
    //headerstyle.Fill.SetPatternBackgroundColor(SLThemeColorIndexValues.Light2Color);
    //headerstyle.Fill.SetPatternForegroundColor(SLThemeColorIndexValues.Dark2Color);
    sl.SetRowStyle(5,5, headerstyle);

    sl.SaveAs("d:\\Test.xlsx");

    MessageBox.Show("Done");
}

这样，我尝试为第一行headerstyle.Fill.SetPatternBackgroundColor(PatternValues.Solid, System.Drawing.Color.IndianRed, System.Drawing.Color.Gray);添加颜色，但是没有用。

再次我也尝试过这种方式headerstyle.Fill.SetPatternForegroundColor(SLThemeColorIndexValues.Dark2Color);，但是没有用。

但是我以这种方式headerstyle.Font.Bold = true;将第一行的字体设置为粗体，但它在第一行中未应用颜色。我在哪里弄错了？

我的openXml版本2.5.5631.0和SpreadsheetLight版本3.4.9.0

请把我推向正确的方向。谢谢

现在已解决问题，并在此处添加了工作代码。         // Install-Package DocumentFormat.OpenXml-版本2.8.1

    dt.Columns.Add("Size (MB)", typeof(double));
    dt.Columns.Add("Cost", typeof(decimal));

    for (int i = 0; i < 20; ++i)
    {
        dt.Rows.Add(string.Format("Prod{0}", i+1),
            string.Format("{0}.{1}.{2}.{3}", rand.Next(256), rand.Next(256), rand.Next(256), rand.Next(256)),

Answer 1

根据文档，您应该致电：

headerstyle.Fill.SetPattern(PatternValues.LightTrellis, SLThemeColorIndexValues.Accent1Color, SLThemeColorIndexValues.Accent2Color);

这是一个例子：

SLDocument sl = new SLDocument();

SLStyle style1 = sl.CreateStyle();
style1.Fill.SetPattern(PatternValues.Solid, SLThemeColorIndexValues.Accent2Color, SLThemeColorIndexValues.Accent4Color);

// set row 4 with 1st style
sl.SetRowStyle(4, style1);
sl.SaveAs("StyleRowColumnCell.xlsx");

我从他们的网站的this example中提取了此示例。
