是否可以创建新工作表并将文件中的数据添加到其中？

    $objReader = new PHPExcel_Reader_Excel5();
    $objReader->setLoadSheetsOnly('Page1');
    $objPHPExcel = $objReader->load('template.xls');

    $objReader->setLoadSheetsOnly('Page2');
    $objWorksheet = $objPHPExcel->createSheet();
    $objWorksheet->setTitle('Sheet'.$sheetIndex);
    $objPHPExcel = $objReader->load($timesheetTemplatePath);

createSheet

$objWorksheet = $objPHPExcel->createSheet(1);
