推荐答案
不要的OnStartPage 添加内容，而不是在设置变量，并将它们在<$ C $写C>的OnEndPage 。这是iText的书，但它很难找到超越新闻组认为，这一在线文档。见<一href=\"http://itext-general.2136553.n4.nabble.com/Use-PdfPageEventHelper-onStartPage-tp4229511p4230850.html\"相对=nofollow>这个和<一个href=\"http://itext-general.2136553.n4.nabble.com/Will-it-be-a-problem-if-I-add-content-in-onStartPage-tp2162582p2162583.html\"相对=nofollow>这个
Do not add content in OnStartPage, instead set variables in that and write them in OnEndPage. This is in the iText book but its hard to find online documentation beyond newsgroups that say this. See this and this
修改
@Satinder辛格，这是一个很大code的阅读，如果可以的话，总是试图提炼它下降到code仍然打破了量最小，并删除您的任何特定领域的东西，这样的为会话和全局变量。这么说，我没看过的大部分，但我想我看到您的问题：
@Satinder singh, that's a lot of code to read, if you can, always try to distill it down to the smallest amount of code that still breaks and remove any of your domain-specific stuff such as session and global variables. That said, I didn't read most of it but I think I spotted your problem:
PdfPTable table2 = new PdfPTable(3);
table2.TotalWidth = document.PageSize.Width - document.LeftMargin;
table2.AddCell("cell Value 1");
table2.AddCell("Cell Value 2 ");
table2.WriteSelectedRows(0, -1, document.LeftMargin + 200, document.PageSize.Height - 30, writer.DirectContent);
以上，你要创建一个三列的表格，但你只有两个单元添加到它。 iTextSharp的是有点挑剔其细胞的正确数目所以要么将其更改为一个两列的表格或添加第三个单元格中。
Above, you're creating a three column table but you're only add two cells to it. iTextSharp is a little picky about having the correct number of cells so either change it to a two column table or add a third cell.
这篇关于在页脚添加pdfpTable同时使用iTextSharp的创建PDF的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
