：

 `ColumnText columnTable=new ColumnText(writer.getDirectContent()); 
     columnTable.setSimpleColumn(50,170,544,380); 
     columnTable.addElement(table); 
     int status=columnTable.go(); 
     while(columnTable.hasMoreText(status)) 
     { 
      Footer();//before leaving the page add footer in current page 
      document.newPage();//create a new page 
      Header();//adding header to new page 
      putDate();//adding date to new page 
      columnTable.setSimpleColumn(50,650,544,150);// adding position of table in new page 
      status=columnTable.go();//start to paste all table data 
      Footer();// before leaving the new page add footer on current page/new page 
     }`
