table borders not expanding properly in pdf using itext

I would like to generate pdf which contains table with border and having more data in that table so when generating pdf it is generated in two pages. But the problem is table borders not expanding page to page i.e, in the next page borders(horizontal),previous page vertical border framed again which is wrong. Horizontal in next page, Vertical in previous page should not come.

Please find the attached pdf file and html file for reference.

You want a table that looks like this custom_border2.pdf.

As explained in my comments, you need to set the borders of the cell to NO_BORDER, either by changing the default cell:

table.getDefaultCell().setBorder(Rectangle.NO_BORDER);

Or by changing the properties of specific cells:

PdfPCell cell = new PdfPCell(new Phrase(TEXT));
cell.setBorder(Rectangle.NO_BORDER);

Or both.

Then you have to create a table event:

class BorderEvent implements PdfPTableEventAfterSplit {

    protected boolean bottom = true;
    protected boolean top = true;

    public void splitTable(PdfPTable table) {
        bottom = false;
    }

    public void afterSplitTable(PdfPTable table, PdfPRow startRow, int startIdx) {
        top = false;
    }

    public void tableLayout(PdfPTable table, float[][] width, float[] height,
            int headerRows, int rowStart, PdfContentByte[] canvas) {
        float widths[] = width[0];
        float y1 = height[0];
        float y2 = height[height.length - 1];
        float x1 = widths[0];
        float x2 = widths[widths.length - 1];
        PdfContentByte cb = canvas[PdfPTable.LINECANVAS];
        cb.moveTo(x1, y1);
        cb.lineTo(x1, y2);
        cb.moveTo(x2, y1);
        cb.lineTo(x2, y2);
        if (top) {
            cb.moveTo(x1, y1);
            cb.lineTo(x2, y1);
        }
        if (bottom) {
            cb.moveTo(x1, y2);
            cb.lineTo(x2, y2);
        }
        cb.stroke();
        cb.resetRGBColorStroke();
        bottom = true;
        top = true;
    }
}

The splitTable() and afterSplitTable() method will keep track if a top or bottom border needs to be drawn. The actual borders are drawn in the tableLayout() method.

You need to set this table event right after creating the table:

PdfPTable table = new PdfPTable(2);
BorderEvent event = new BorderEvent();
table.setTableEvent(event);

Now you will have the desired behavior as explained in my initial comment. You can find the full code sample here. I have provided a more complex example here.
