如何使用iext sharp创建下面提到的表格。下面是我的代码，但我很紧张。帮我做一个这样的表格。我的代码

        var subTable2 = new PdfPTable(new float[] { 100, 100, 100, 100, 100, 100,100,100 });
        subTable2.TotalWidth = 510f;
        subTable2.LockedWidth = true;
        subTable2.DefaultCell.HorizontalAlignment = Element.ALIGN_CENTER;
        subTable2.AddCell(new Phrase("Examination", time51));
        subTable2.DefaultCell.HorizontalAlignment = Element.ALIGN_CENTER;
        subTable2.AddCell(new Phrase("Board", time51));
        subTable2.DefaultCell.HorizontalAlignment = Element.ALIGN_CENTER;
        subTable2.AddCell(new Phrase("Month and Year of Passing", time51));
        subTable2.DefaultCell.HorizontalAlignment = Element.ALIGN_CENTER;
        subTable2.AddCell(new PdfPCell(new Phrase("Mark", time51)));
        PdfPTable nested = new PdfPTable(1);
        nested.AddCell("");
        nested.AddCell("Obtained");
        nested.AddCell("Out of");
        PdfPCell nesthousing = new PdfPCell(nested);
        nesthousing.Padding = 0f;
        subTable2.AddCell(nesthousing);
        subTable2.DefaultCell.HorizontalAlignment = Element.ALIGN_CENTER;
        subTable2.AddCell(new Phrase("Percentage", time51));
        subTable2.DefaultCell.HorizontalAlignment = Element.ALIGN_CENTER;
        subTable2.AddCell(new Phrase("Calss/Grade", time51));
        doc.Add(subTable2);

请查看SimpleTable12。它创建一个如下所示的表：simple_table12.pdf

你仍然可以通过使用填充或引入下行/上升信息来微调单元格的高度，但这些都是细节。重要的是：如何组织细胞？

我写了这个小便捷方法：

public PdfPCell createCell(String content, int colspan, int rowspan, int border) {
    PdfPCell cell = new PdfPCell(new Phrase(content, font));
    cell.setColspan(colspan);
    cell.setRowspan(rowspan);
    cell.setBorder(border);
    cell.setHorizontalAlignment(Element.ALIGN_CENTER);
    return cell;
}

您传递了一些内容，一个colspan，一个rowspan和border信息，它会为您创建所需的PdfPCell。这使我们可以创建更易于阅读的代码：

public void createPdf(String dest) throws IOException, DocumentException {
    font = new Font(FontFamily.HELVETICA, 10);
    Document document = new Document();
    PdfWriter.getInstance(document, new FileOutputStream(dest));
    document.open();
    PdfPTable table = new PdfPTable(8);
    table.setWidthPercentage(100);
    table.addCell(createCell("Examination", 1, 2, PdfPCell.BOX));
    table.addCell(createCell("Board", 1, 2, PdfPCell.BOX));
    table.addCell(createCell("Month and Year of Passing", 1, 2, PdfPCell.BOX));
    table.addCell(createCell("", 1, 1, PdfPCell.TOP));
    table.addCell(createCell("Marks", 2, 1, PdfPCell.TOP));
    table.addCell(createCell("Percentage", 1, 2, PdfPCell.BOX));
    table.addCell(createCell("Class / Grade", 1, 2, PdfPCell.BOX));
    table.addCell(createCell("", 1, 1, PdfPCell.BOX));
    table.addCell(createCell("Obtained", 1, 1, PdfPCell.BOX));
    table.addCell(createCell("Out of", 1, 1, PdfPCell.BOX));
    table.addCell(createCell("12th / I.B. Diploma", 1, 1, PdfPCell.BOX));
    table.addCell(createCell("", 1, 1, PdfPCell.BOX));
    table.addCell(createCell("", 1, 1, PdfPCell.BOX));
    table.addCell(createCell("Aggregate (all subjects)", 1, 1, PdfPCell.BOX));
    table.addCell(createCell("", 1, 1, PdfPCell.BOX));
    table.addCell(createCell("", 1, 1, PdfPCell.BOX));
    table.addCell(createCell("", 1, 1, PdfPCell.BOX));
    table.addCell(createCell("", 1, 1, PdfPCell.BOX));
    document.add(table);
    document.close();
}

如您所见，这是计算正确的colspan和rowspan值以及应用正确边框的问题。
