java - iText setRowspan not working for tables in headers? -


exactly same code used create pdfptable main body of document , document's page header. table rendered in main body doesn't seem take account setrowspan values in header.

below paste screenshot of produced pdf and, after that, minimal standalone program used generate pdf.

pdf output

enter image description here

code

import java.io.*; import com.itextpdf.text.*; import com.itextpdf.text.pdf.*;  class headerandfooter extends pdfpageeventhelper{      private pdfptable header;      public headerandfooter() throws exception {         header = foomain.createtable();         header.settotalwidth(530);     }      @override     public void onendpage(pdfwriter writer, document document) {         pdfcontentbyte cb = writer.getdirectcontent();         float x   = document.leftmargin();         float hei = header.gettotalheight();         float y   = document.top()+hei;         header.writeselectedrows(0, -1, x , y, cb);     } }  public class foomain {      public static void main(string[] args) throws exception {         document doc = new document(pagesize.a4, 30, 30, 150, 40);         pdfwriter writer = pdfwriter.getinstance(doc, new fileoutputstream("./brokentableinheader.pdf"));         writer.setpageevent(new headerandfooter());         doc.open();         doc.add(createtable());         doc.close();     }      public static pdfptable createtable() throws exception {         pdfptable table = new pdfptable(2);         pdfpcell cell = new pdfpcell(new phrase("cell spanning 2 rows"));          cell.setrowspan(2);         table.addcell(cell);         table.addcell( new phrase ("a"));         table.addcell( new phrase ("b"));         return table;     } }

found answer in this question (use columntext::go instead of pdfptable::writeselectedrows)

here's excerpt working code:

columntext column = new columntext(writer.getdirectcontent()); column.addelement(footer); column.setsimplecolumn (0, 0, 630, 80); column.go();

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
