itextsharp 将 Pdfptable 放置在所需位置

Question

标题内容和 Pdftable 重叠

我该如何放置 PdfPTable 在 pdf 页面中的任何位置使用 (x, y) 定位，如 (100, 200) 或 (15, 100) 在pdf页面上的任何地方？

使用 PdfEventHelper 的标题表

public override void OnEndPage(PdfWriter writer, Document document)
{
    AddHeader(writer, document);
}

public void AddHeader(PdfWriter writer, Document document)
{
    // set no of rows
    PdfPTable headerTable = new PdfPTable(1);
    // set the width
    headerTable.TotalWidth = document.PageSize.Width;
    headerTable.DefaultCell.HorizontalAlignment = Element.ALIGN_CENTER;

    PdfPCell company = new PdfPCell(new Phrase(new Chunk("Name", fontArial)));
    company.HorizontalAlignment = Element.ALIGN_CENTER;
    company.BorderWidth = 0;
    headerTable.AddCell(company);

    PdfPCell report = new PdfPCell(new Phrase(new Chunk("PrintedDate", fontArial)));
    report.HorizontalAlignment = Element.ALIGN_CENTER;
    report.BorderWidth = 0;
    headerTable.AddCell(report);

    headerTable.TotalWidth = document.PageSize.Width - 20;

    // write rows to the pdf output stream
    Rectangle pageSize = document.PageSize;
    headerTable.WriteSelectedRows(0, -1, 0, (document.PageSize.Height - 10), writer.DirectContent);
}

在我的主要类(class)中，我这样做

PdfWriter pdfWriter = PdfWriter.GetInstance(document, new FileStream(pdfFile, FileMode.Create));

pdfWriter.PageEvent = page;

document.Open()

下一步 我在这里添加一个 pdftable

PdfPTable HeaderTable = new PdfPTable(2);
HeaderTable.DefaultCell.VerticalAlignment = Element.ALIGN_MIDDLE;
HeaderTable.TotalWidth = pageSize.Width - 80;
HeaderTable.SetWidthPercentage(new float[] {45, 45}, pageSize);

PdfPCell HeaderLeftCell = new PdfPCell(new Phrase(8, HeaderLeft, HeaderFont));
HeaderLeftCell.Padding = 5;
HeaderLeftCell.PaddingBottom = 8;
HeaderLeftCell.BorderWidthRight = 0;
HeaderTable.AddCell(HeaderLeftCell);

PdfPCell HeaderRightCell = new PdfPCell(new Phrase(8, HeaderRight, HeaderFont));
HeaderRightCell.HorizontalAlignment = Element.ALIGN_RIGHT;
HeaderRightCell.Padding = 5;
HeaderRightCell.PaddingBottom = 8;
HeaderRightCell.BorderWidthLeft = 0;
HeaderTable.AddCell(HeaderRightCell);

HeaderTable.WriteSelectedRows(0, -1, pageSize.GetLeft(40), pageSize.GetTop(50), cb);

结果是 Header Content 和 pdftable 重叠

Answer 1

如 itext docs 中所述——

To avoid having the cell border and the content overlap, if you are having thick cell borders, call the setUserBorderPadding(true), like this:

cell.setUserBorderPadding(true);
