I want to create a PDF table in Landscape with 16 columns using Java
iText API.

I use class PdfPTable, but it looks like the maximum number of columns
is 12. If I set the
number of columns go beyond 12, then I get ExceptionConverter:
java.io.IOException: The document has no pages.

Is that true?

Here's my code fragment:

Document document = new Document(PageSize.A4.rotate(), 10, 10, 10, 10);
int NumColumns = 13;
try {
	PdfPTable datatable = new PdfPTable(NumColumns);
	datatable.getDefaultCell().setPadding(3);
	int headerwidths[] = {9, 4, 8, 10, 8, 11, 9, 7, 9, 10, 4, 5, 5}; //
percentage
	datatable.setWidths(headerwidths);
	datatable.setWidthPercentage(100); // percentage
	for (int x = 0; x < NumColumns; x++) {
		datatable.addCell("hello");
	}
	document.add(datatable);
}
catch(Exception e) {
	e.printStackTrace();
}


Any ideas? Or better approach to my problem? Maybe this is the
limitations of iText API??

Please advice. thanks!!

Your problem is that your headerwidths-Array has more elements than the 
datatable. iText does not display Table-Rows that are not "complete". 
Therefore, the table is empty, and therefore, the page is empty. And 
iText does not like empty documents.
