You can't add content using PdfCopy, but you already have an instance of
PdfStamper, why don't you add the PdfPTable using stamper.getContentOver()?

Hello,
thank you very much for your tip. It works now =) with just a little change in
the code.
By the way another question. Just in case I am adding a very large table with
the spamper, only the first party of the table will be displayed, because the
stamper only works on one page at a time... is there a possibility to add the
rest of my content on a new inserted page using the current stamper object...
my code currently looks like:
cb = stamper.getOverContent(1);
ct = new ColumnText(cb);
ct.setAlignment(Element.ALIGN_CENTER);
ct.setSimpleColumn(36, 36, PageSize.A4.width()-36,
PageSize.A4.height()-300);
//Tabellenkörper erzeugen
PdfPTable tableMainHeader = new PdfPTable(7);
tableMainHeader.setWidthPercentage(100f);
tableMainHeader.setWidths(new int[] { 15, 35, 10, 10,
10, 10, 10 });
PdfPCell cell = new PdfPCell();
for (int m = 0; m < beteiligungEigenschaften.length;
m++)
{
for (int l = 0; l < 7; l++)
{
cell = new PdfPCell();
cell.setBackgroundColor(textColor);
cell.setMinimumHeight(30f);
cell.addElement(new
Chunk(beteiligungEigenschaften[m][l].toString()));
tableMainHeader.addCell(cell);
}
}
ct.addElement(tableMainHeader);
//render
int currentColumn =0;
while (true)
{
int status = ct.go();
if ((status & ColumnText.NO_MORE_TEXT) != 0)
{
break;
}
++currentColumn;
if(currentColumn>=1){
break;
}
}
stamper.setFormFlattening(true);
stamper.close();
Only the first ca 20 rows of ca 660 are displayed... I tried to use the
go(true) simulation to find out whether a new page has to be started but i
didn't get it to work :(
in hope there is a solution
regard
stephan
