PHPExcel setRowHeight（-1）和setWrapText（true）不会自动调整行的高度

已经尝试了以下，它没有帮助，接下来我应该尝试什么？ 我错过了什么？

$objPHPExcel->getActiveSheet()->setCellValue('A10', 'Value1, Value2, Value3, Value4, Value5'); $objPHPExcel->getActiveSheet()->getRowDimension(10)->setRowHeight(-1); $objPHPExcel->getActiveSheet()->getStyle('A10')->getAlignment()->setWrapText(true); 

然后

 $objPHPExcel->getDefaultStyle()->getAlignment()->setWrapText(true); foreach($objPHPExcel->getActiveSheet()->getRowDimensions() as $rd) { $rd->setRowHeight(-1); } 

也

 $objPHPExcel->getActiveSheet(0)->getStyle('A1:D10')->getAlignment()->setWrapText(true); $objPHPExcel->getActiveSheet()->getRowDimension(1)->setRowHeight(-1); $objPHPExcel->getActiveSheet()->getRowDimension(2)->setRowHeight(-1); $objPHPExcel->getActiveSheet()->getRowDimension(3)->setRowHeight(-1); $objPHPExcel->getActiveSheet()->getRowDimension(4)->setRowHeight(-1); $objPHPExcel->getActiveSheet()->getRowDimension(5)->setRowHeight(-1); $objPHPExcel->getActiveSheet()->getRowDimension(6)->setRowHeight(-1); $objPHPExcel->getActiveSheet()->getRowDimension(7)->setRowHeight(-1);
