在EPPlus中对单个单元格应用多种颜色？

using (var package = new ExcelPackage())
{
    var worksheet = package.Workbook.Worksheets.Add("Sheet1");

    var cell = worksheet.Cells["A1"];
    cell.IsRichText = true; // 设置单元格为富文本

    var richText = cell.RichText.Add("Hello");
    richText.Color = System.Drawing.Color.Red;

    richText = cell.RichText.Add(" World");
    richText.Color = System.Drawing.Color.Blue;

    package.SaveAs(new FileInfo(@"Path\to\your\file.xlsx"));
}
