Comment insérer une formule dans une feuille Excel à l'aide de phpexcel

J'ai vérifié de nombreux sites pour trouver une solution à mon problème, mais je n'ai pas trouvé de solution appropriée. Je veux insérer une formule qui calculera le total des notes obtenues par les étudiants. Les notes seront entrées par les enseignants. J'ai écrit le code php qui télécharge le fichier Excel après avoir inséré les noms des étudiants à partir de la base de données et de maxmarks. Mon fichier Excel ressemble à ceci, veuillez voir l'image car je n'ai pas 10 points de réputation Je ne suis pas autorisé à insérer l'image dans le message, veuillez suivre ce lien http://cbsecsnip.in/Capture.JPG La colonne Marques est vide où l'enseignant marquera que les autres données sont extraites de la base de données et la colonne Pourcentage a besoin d'une formule qui calculera automatiquement les notes lorsque l'enseignant entrera des notes. La colonne remplie et la colonne Pourcentage sont protégées. J'utilise PHPExcel. Voici le code php qui génère ce fichier Excel

@Mark Baker Merci de montrer la façon dont j'ai essayé et fait comme ça -

$calculatRow='';
    for($ctr=0;$ctr < count($marksColumnArr);$ctr++)
    {
    $calculatRow.='(($'.$marksColumnArr[$ctr].'##/$'.$maXmarksColumnArr[$ctr].'$##)*'.$divisionVal[$ctr].')+';      
}
$calculateArrbyRow=substr($calculatRow,0,-1);    
// Replicate formula by row

 for($j=5;$j<count($totalStudents)+5;$j++){
   $formula=str_replace('##',$j,$calculateArrbyRow);
   $cell=PHPExcel_Cell::stringFromColumnIndex($coumnStart+12);
  $objPHPExcel->getActiveSheet()->setCellValue($cell.$j, '='.$formula);
 }    
$coumnStart=($coumnStart-1)+13; $subjectCtr++;
}

Lisez la section 4.6.4 de la documentation du développeur et des exemples comme 03formulas.php.

Vous pouvez écrire une formule comme vous l'écrivez dans Excel lui-même, stockez simplement la formule préfixée avec = Dans la cellule

par exemple.

$objPHPExcel->getActiveSheet()
    ->setCellValue(
        'E10',
        '=SUM(A10:E9)'
    );

Écrira la formule =SUM(A10:E9) dans la cellule E10

Lorsque vous écrivez une formule dans une cellule, n'oubliez pas que:

  • Le séparateur décimal est . (Point)
  • Le séparateur d'arguments de fonction est , (Virgule)
  • Le séparateur de ligne de la matrice est ; (Point-virgule)
  • Les noms de fonction en anglais doivent être utilisés

MODIFIER 

for ($row = 1; $row <= 10; $row++) {
    $objPHPExcel->getActiveSheet()
        ->setCellValue(
            'J' . $row,
            '=SUM(A'.$row.':C'.$row.')/10 + SUM(D'.$row.':F'.$row.')/20 + SUM(G'.$row.':I'.$row.')/60'
        );
}
