[iText-questions] Exception : how to add a headertable on top to nested table when it goes to new page:Very urgent

[Kurakula, Suneetha (HCF)]

Hi All,   I am using nested Table for displaying various kinds of data. In the nested table first table is header table which defines column names. So when it goes to new page nested page should call Header table after it should continue from other table where it was broken.   Here is my code.But it doen't seems to work.                                         Table headerTable = getHeaderTable();                                     maintable.insertTable(headerTable);                                                                         Table donTable = getDonTable(nurseExpenses);                                     maintable.insertTable(donTable);                                                                         Cell cell = new Cell(" "); //this is to give gap between two tables                                     maintable.addCell(cell);                                       Table rnTable = getRNTable(nurseExpenses);                                     maintable.insertTable(rnTable);                                       cell = new Cell(" ");                                     maintable.addCell(cell);                                       Table lpnTable = getLPNTable(nurseExpenses);                                     maintable.insertTable(lpnTable);                                       cell = new Cell(" ");                                     maintable.addCell(cell);                                       Table cnaTable = getCNATable(nurseExpenses);                                                             if (!writer.fitsPage(maintable)) {                                                 System.out.println("Inside fit table");                                                 document.add(maintable);                                                 document.newPage();                                                 maintable.insertTable(headerTable);                           }                                     maintable.insertTable(cnaTable);                                                             document.add(maintable);   Here is the exception I am getting   7:32:07,956 ERROR [STDERR] java.lang.ClassCastException 7:32:07,956 ERROR
