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!!
