iText-5.0.1 +用虚线表示PdfPTable的边框 [英] iText-5.0.1 + Make the border of PdfPTable with dotted line

问题描述

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？

Is there any way to make the border of a cell with dotted line (e.g _ _ _ _ _ _ _ _ _ _ _ _) instead of solid line ( e.g ________________ ) in iText-5.0.1????

推荐答案

用破折号加下划线的单元格：

Cell underlined with dashes:

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();
    }
}
