$objPHPExcel = new PHPExcel();
$sheet = $objPHPExcel->getActiveSheet();
$sheet->setCellValueByColumnAndRow(0, 1,
"test test test test test test test test");
$sheet->getColumnDimension('A')->setAutoSize(true);
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save("test.xlsx");
$objPHPExcel = new PHPExcel();
$sheet = $objPHPExcel->getActiveSheet();
$sheet->setCellValueByColumnAndRow(0, 1,
"test test test test test test test test");
//this breaks the width calculation
$sheet->mergeCells('A1:B1');
$sheet->getColumnDimension('A')->setAutoSize(true);
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save("test.xlsx");
As far as I understand, there is no standard way to set auto size for merged cells. Is there any workaround for this?
You could calculate the column widths before merging the cells using ->calculateColumnWidths()
, and then ->setAutoSize(false)
to make sure that they are not calculated again. The code could look something like this:
// Set the data in the cells
$objPHPExcel->getActiveSheet()->fromArray($sheet, null, 'A1');
// Calculate the column widths
foreach(range('A', 'E') as $columnID) {
$objPHPExcel->getActiveSheet()->getColumnDimension($columnID)->setAutoSize(true);
}
$objPHPExcel->getActiveSheet()->calculateColumnWidths();
// Set setAutoSize(false) so that the widths are not recalculated
foreach(range('A', 'E') as $columnID) {
$objPHPExcel->getActiveSheet()->getColumnDimension($columnID)->setAutoSize(false);
}
// Merge cells
$objPHPExcel->getActiveSheet()->mergeCells("A1:A5");
i personnaly used the size of the value to adapt the size of the cell :
$value = $sheet->getCell('A1')->getValue();
$width = mb_strwidth ($value); //Return the width of the string
$sheet->getColumnDimension('A')->setWidth($width);
Beware if you have made a ->setAutoSize(true)
on the column that you want to modify you need to put it at false before doing any modifications :
$sheet->getColumnDimension('A')->setAutoSize(false);
