Not able to add border for first row only in the table using aspose pdf

Hi, I used the following code to add border for first row only, there is no error while debugging but the border is not showing in the pdf. Aspose.Pdf.Generator.Table keycomp = new Aspose.Pdf.Generator.Table(); keycomp.Rows[0].DefaultCellBorder = new Aspose.Pdf.Generator.BorderInfo((int)Aspose.Pdf.Generator.BorderSide.Bottom, 0.2F); and I am using framework 3.5
