在itextsharp pdf中制作表格

Question

我正在创建一个包含header和footer部分的pdf， 在我的身体部分，我想要一个包含我的datagridview数据的表格。PDF 可能比 3 或 4 页更长。我已经做到了，但问题是，我的表格在一页中显示 2 次。您可以在捕获中看到下面给出的图像。在此处输入图像描述

我的代码是

public partial class Footer : PdfPageEventHelper
{
iTextSharp.text.Image image;

public override void OnEndPage(PdfWriter writer, Document doc1)
{
Document doc = new Document(PageSize.A4, 30f, 30f, 42f, 30f);
doc.Open();
iTextSharp.text.Image footer = iTextSharp.text.Image.GetInstance("dslmfooter.png");
footer.ScaleAbsoluteHeight(40f);
footer.ScaleAbsoluteWidth(520f);
doc.Add(footer);

footerTbl.HorizontalAlignment = Element.ALIGN_CENTER;
PdfPCell cell = new PdfPCell(footer);
cell.Border = 0;
cell.PaddingLeft = 10;
footerTbl.AddCell(cell);
footerTbl.WriteSelectedRows(0, -1, 25, 50, writer.DirectContent);
}
}
public partial class Header : PdfPageEventHelper

public override void OnStartPage(PdfWriter writer, Document doc1)
{

请大家试着帮助我！ 谢谢 ：-(

Answer 1

这是一些 iText7 代码，用于生成跨多个页面的表。
您应该能够将其与代码结合使用以插入页眉和页脚，并为您的用例提供一个工作示例：

public static void main(String[] args) throws Exception {
File file = new File(DEST);
file.getParentFile().mkdirs();
new SplitRowAtEndOfPage().manipulatePdf(DEST);
}
@Override
protected void manipulatePdf(String dest) throws Exception {
Table table = new Table(1);
table.setWidth(550);
// the number of iterations has been changed in order to provide the same as in itext5 example
for (int i = 0; i < 6; i++) {
Cell cell;
if (i == 5) {
cell = new Cell().add("ThreenLinesnHere");
} else {
cell = new Cell().add(Integer.toString(i));
}
table.addCell(cell);
}
PdfDocument pdfDoc = new PdfDocument(new PdfWriter(dest));
Document doc = new Document(pdfDoc, new PageSize(612, 237));
doc.add(table);
doc.close();
}
