调用未定义的方法PHPExcel_Worksheet :: getAlignment（）

Question

I've been trying to make a new line in exporting data to excel file with this code

if ($campaign['type'] == 'blended') {
    $objWorkSheet->setCellValueByColumnAndRow($col++, $row, "$launch_date,
 email: {$email_launch_date}, 
 tm: {$tm_launch_date}");
    $objPHPExcel->getActiveSheet()->getAlignment()->setWrapText(true);   

But this gives me

Type: Error Message: Call to undefined method PHPExcel_Worksheet::getAlignment()

I also try the suggestion here but it doesn't work for me,

what is the right thing to do?

Answer 1

You should be applying styles to individual cells or ranges of cells, not to worksheets (which don't have a style)

if ($campaign['type'] == 'blended') {
    $objWorkSheet->setCellValueByColumnAndRow($col, $row, "$launch_date,
 email: {$email_launch_date}, 
 tm: {$tm_launch_date}");
    $objWorkSheet->getStyle(PHPExcel_Cell::stringFromColumnIndex($col) . $row)
        ->getAlignment()
        ->setWrapText(true);
    $col++;
}
