itextsharp，HTML到pdf对齐单元格

Question

我有一个项目可以将HTML页面导出为PDF
HTML页面有一个包含4列和20行的表，一旦在PDF上导出，这些行就没有对齐，我试图在HMTL中修复，设置宽度但没有结果

这里有一个示例项目可供下载，并且易于尝试
http://www.suale.it/provaAPP/WindowsFormsApp1.zip
这里是HTML页面
http://www.suale.it/provaAPP/TemplateVL.htm 结果在这里 http://www.suale.it/provaAPP/PDF.jpg

怎么了？

这里我用来转换的代码

private void button1_Click(object sender, EventArgs e)
{
    StyleSheet css = new StyleSheet();
    FontFactory.Register(Application.StartupPath + @"\cour.ttf", "CourierN");

    string outputFile = Application.StartupPath + @"\file.pdf";
    string fileHTML = Application.StartupPath + @"\TemplateVL.htm";
    string HTML = File.ReadAllText(fileHTML);

    string filepath = outputFile;
    Document document = new Document(PageSize.A4);
    PdfWriter writer = PdfWriter.GetInstance(document, new FileStream(filepath, FileMode.Create));

    HTML = HTML.Replace("[", "");
    HTML = HTML.Replace("]", "");
    HTML = HTML.Replace("@", "");

    document.Open();
    StringReader sr = new StringReader(HTML);           
    XMLWorkerHelper.GetInstance().ParseXHtml(writer, document, sr);            
    document.Close();

    byte[] Bites = creaPDF(Application.StartupPath+ @"\file.css",HTML );
    File.WriteAllBytes(outputFile, Bites);


    var fol = new ProcessStartInfo(outputFile);
    fol.WindowStyle = ProcessWindowStyle.Maximized;
    Process.Start(fol);
}
