粗体和斜体在 excel 中与 EPPLUS 不兼容

Question

我正在使用下面的代码更新 excel 数据格式，这里我希望标题为粗体，整个数据为斜体格式，但是当我运行代码中的所有功能时除了粗体和斜体，它似乎工作正常。代码也完成了执行，没有任何错误，但在 excel 文件中 none 的单元格的数据为粗体或斜体格式。

    public void FormatExcel()
    {
        string currentDate = DateTime.Now.ToString("yyyyMMdd");
        FileInfo File = new FileInfo("G:\Selenium\Test66.xlsx");
        using (ExcelPackage excel = new ExcelPackage(File))
        {
            ExcelWorksheet worksheet = excel.Workbook.Worksheets[currentDate];
            int totalRows = worksheet.Dimension.End.Row;
            int totalCols = worksheet.Dimension.End.Column;
            var headerCells = worksheet.Cells[1, 1, 1, totalCols];
            var headerFont = headerCells.Style.Font;
            headerFont.Bold = true;
            headerFont.Italic = true;
            headerFont.SetFromFont(new Font("Times New Roman", 12));
            headerFont.Color.SetColor(Color.DarkBlue);
            var headerFill = headerCells.Style.Fill;
            headerFill.PatternType = ExcelFillStyle.Solid;
            headerFill.BackgroundColor.SetColor(Color.Gray);
            var dataCells = worksheet.Cells[2, 1, totalRows, totalCols];
            var dataFont = dataCells.Style.Font;
            dataFont.Italic = true;
            dataFont.SetFromFont(new Font("Times New Roman", 10));
            dataFont.Color.SetColor(Color.DarkBlue);
            var dataFill = dataCells.Style.Fill;
            dataFill.PatternType = ExcelFillStyle.Solid;
            dataFill.BackgroundColor.SetColor(Color.Silver);
            var allCells = worksheet.Cells[1, 1, totalRows, totalCols];
            allCells.AutoFitColumns();
            allCells.Style.HorizontalAlignment = ExcelHorizontalAlignment.Center;
            var border = allCells.Style.Border;
            border.Top.Style = border.Left.Style = border.Bottom.Style = border.Right.Style = ExcelBorderStyle.Thin;
            excel.Save();
        }
    }

Answer 1

问题是您 setting/overwriting 字体在您设置 bold/italic 之后。只需像这样先设置字体：

headerFont.SetFromFont(new Font("Times New Roman", 12)); //Do this first
headerFont.Bold = true;
headerFont.Italic = true;

或者你甚至可以像这样缩短它：

headerFont.SetFromFont(new Font("Times New Roman", 12, FontStyle.Italic | FontStyle.Bold));

Answer 2

headerFont.SetFromFont("Times New Roman", 16, true);
