        //column.setcelleditor(new comboboxcelleditor(combobox2));       //  combobox2.setselecteditem("s");         //column11.setcelleditor(new defaultcelleditor(combobox2));          //set tool tips sport cells.        // defaulttablecellrenderer renderer =         //        new defaulttablecellrenderer();       //  renderer.settooltiptext("click combo box");         // eachroweditor11 roweditor2 = new eachroweditor11(tablemappingsheet);       //  roweditor2.seteditorat(3, new defaultcelleditor(combobox2));       //  roweditor2.seteditorat(4, new defaultcelleditor(combobox2));      //   roweditor2.seteditorat(5, new defaultcelleditor(combobox2));       //  tablemappingsheet.getcolumnmodel().getcolumn(2).setcelleditor(roweditor2);       //  column11.setcellrenderer(renderer);         /*mycellrenderer test  = new mycellrenderer();         defaultcelleditor defaultcelleditor=new defaultcelleditor(combobox2);         jlist jlist  = new jlist(lst.toarray());         column11.setcelleditor((tablecelleditor) test.getlistcellrenderercomponent(jlist, null, -1, true, true));         */         //lst.        // column11.setcellrenderer(lst);         // column11.setcellrenderer()         java2sautocombobox combobox = new java2sautocombobox(lst);         combobox.setdatalist(lst);         column11.setcelleditor(new defaultcelleditor(combobox));        // tablemappingsheet.repaint();           tablecolumn columnforlookupvalidation = tablemappingsheet.getcolumnmodel().getcolumn(4);          columnforlookupvalidation.setcelleditor(new comboboxcelleditor(comboboxforlookupvalidation));          //table.getcolumnmodel().addcolumnmodellistener(columnmodellistener);
