Pdf Exporter format
Haijian Wang: Hello Tomas, are you talking about this Exporter addon https://vaadin.com/directory#!addon/exporter?
If yes, sorry currently it doesn't have such feature yet. I will take this into consideration and make an improvement in the future.
Finally, i do it. I had to change this method in PdfFileBuilder
@Override
protected void resetContent() {
document = new Document(PageSize.A4.rotate());
table = new PdfPTable(getNumberofColumns());
try {
PdfWriter.getInstance(document, new FileOutputStream(file));
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (DocumentException e) {
e.printStackTrace();
}
document.open();
}
