我试图用页眉中的页码创建一个word文档。我使用SimpleField插入页码和页数。 但是，与文本不同（如下面的图片所示），这些字段不受RunProperties中定义的颜色和字体大小的影响。

如何格式化SimpleField？

谢谢

    private static void CreateReport(string filename)
    {
        using (var mem = new MemoryStream())
        {

            using (var wordDocument = WordprocessingDocument.Create(mem,WordprocessingDocumentType.Document,true))
            {
                // Add a main document part. 
                MainDocumentPart mainPart = wordDocument.AddMainDocumentPart();

                // Create the document structure
                mainPart.Document = new Document();
                mainPart.Document.Body = new Body();

                //Create paragraph for header
                var paragraph = new Paragraph();

                //Add paragraph to header
                AddParagraphToHeader(mainPart,paragraph);

                //Save document
