Question

有没有办法在iText-5.0.1中用虚线（例如_ _ _ _ _ _ _ _ _ _ _ _）代替实线（例如________________）制作单元格的边框？

Answer 1

你可以安排像添加小高度和text =“---------”

的新段落

PdfPCell Cell = new PdfPCell(new Paragraph("------"));
Cell.Height = 0.2f;

您也可以使用PdfPCellEvent自己绘制边框。要添加不同的图层。请在此处查看API：http://api.itextpdf.com/com/itextpdf/text/pdf/PdfPCellEvent.html

Answer 2

如建议的那样，使用PdfPCellEvent。下面的代码应该可以帮助您完成大部分工作。 Cell event example.通过覆盖单元格事件，您基本上可以告诉iText您认为应该如何绘制单元格。无论何时将任何单元格添加到表格中，它们都将遵循您的规则。

 class CustomCell implements PdfPCellEvent {
 public void cellLayout(PdfPCell cell, Rectangle rect,
                   PdfContentByte[] canvas) {
                   PdfContentByte cb = canvas[PdfPTable.LINECANVAS];
                   cb.setLineDash(new float[] {3.0f, 3.0f}, 0);           
                   cb.stroke();
          }
 }

 public class Main {

         public static void main(String[] args) throws Exception {
             Document document = new Document();
             PdfWriter.getInstance(document, new FileOutputStream("output.pdf"));
             document.open();
             CustomCell border = new CustomCell();

             PdfPTable table = new PdfPTable(6);
             PdfPCell cell;

             for (int i = 1; i <= 6; i++) {
               cell = new PdfPCell(new Phrase("test"));              
               cell.setCellEvent(border);
               table.addCell(cell);
             }

             document.add(table);
             document.close();
     }
}

Answer 3

细胞用破折号加下划线：

public class UnderlinedCell implements PdfPCellEvent {

    public void cellLayout(PdfPCell cell, Rectangle position,
        PdfContentByte[] canvases) {
        PdfContentByte canvas = canvases[PdfPTable.LINECANVAS];
        canvas.setLineWidth(0.5f);
        canvas.setLineDash(3f, 3f);
        canvas.moveTo(position.getLeft(), position.getBottom());
        canvas.lineTo(position.getRight(), position.getBottom());

        canvas.stroke();
    }
}

Answer 4

PdfPCell Border1 = new PdfPCell(new Paragraph("-----------------------------------------------------------------------------------------------------------------------"));
            Border1.Border = 0;
            Border1.VerticalAlignment = 3;
            Border1.FixedHeight = 5F;
            Border1.PaddingLeft = -5;
            Border1.PaddingRight = -5;
            Border1.PaddingBottom = -5;
            Border1.PaddingTop = -5;
