如果 iTextSharp 包含很大，如何在下一页上设置大表格
[英]how to set large table on next pages if contain is large with iTextSharp
问题描述
我通过 PdfPageEventHelper 在我的文档上添加了页眉和页脚。
该文档有几个在运行时填充的“大”表。
我试图简单地通过“documen.Add(table)”来添加这些表格，但我的页眉和页脚结果被覆盖了。
我已经尝试了两种方法来添加表（WriteSelectedRows 和 document.Add(myPdfPtable)）。
这是 Head 的 PageEventHelper 代码：
public override void OnEndPage(PdfWriter writer, Document doc)
{
Phrase phrase = null;
PdfPCell cell = null;
PdfPTable maintable = new PdfPTable(2);
maintable.TotalWidth = 500f;
maintable.LockedWidth = true;
maintable.SetWidths(new float[] { 50f, 400f });
#region checklogo
if (IsLogo!=0)
{
// code for display head like logo, etc
}
#endregion CheckSchoolNameandAddress
maintable.WriteSelectedRows(0, -1, 50, 835, writer.DirectContent);
Color color = new Color(System.Drawing.ColorTranslator.FromHtml("#A9A9A9"));
DrawLine(writer, 25f, 780f, doc.PageSize.Width - 25f, 780f,color);
DrawLine(writer, 25f, 780f, doc.PageSize.Width - 25f, 780f, color);
}
这是页脚的 PageEventHelper 代码：
public override void OnEndPage(PdfWriter writer, Document doc)
{
Phrase phrase = null;
PdfPCell cell = null;
PdfPCell cell1 = null;
PdfPCell cell2 = null;
int pageN = writer.PageNumber;
String text = "Page " + pageN;
PdfPTable foootertable = new PdfPTable(3);
foootertable.TotalWidth = 500f;
foootertable.LockedWidth = true;
foootertable.SetWidths(new float[] { 50f, 60f, 50f });
#region checkprintedbyReportNamePageNo
if (Isfooter != 0)
{
// code for footer like pageno, etc
}
#endregion CheckprintedbyReportNamePageNo
foootertable.WriteSelectedRows(0, -1, 30,30, writer.DirectContent);
color = new Color(System.Drawing.ColorTranslator.FromHtml("#A9A9A9"));
DrawLine(writer, 25f, 32f, doc.PageSize.Width - 25f, 32f, color);
DrawLine(writer, 25f, 32f, doc.PageSize.Width - 25f, 32f, color);
}
显示在所有页面上的表格代码，如 reportdiaplay

我以前曾遇到过这个问题，但是我能提出的唯一解决方案是确定现在在一个页面上可以容纳许多行而不会弄乱布局，并且我添加了许多表格来将所有行放入文档中。
如评论中所述（@Bruno Lowagie）iTextSharp DOES提供了一种控制表分页的机制。
我相信它的正确答案是： iTextSharp的页眉，页脚和大表
iText\\iTextSharp 表格被分成两页的情况如何处理？
