const tableModel = TableFactory.createTableModel({ rows, columnDefs, tableOptions});
const tableScope = new TableScope( divEle, tableModel, new SimpleDomService(), tableOptions, new EventAdapter());
tableScope.firstInit();const tableApi = tableScope.getApi();
downloadExcelBtn.addEventListener("click", (event) => { tableApi.downloadExcel();});
