                $validation->setAllowBlank(false);
                $validation->setShowInputMessage(true);
                $validation->setShowErrorMessage(true);
                $validation->setShowDropDown(true);
                $validation->setErrorTitle('Input error');
                $validation->setError('Value is not in list.');
                $validation->setPromptTitle('Pick from list');
                $validation->setPrompt('Please pick a value from the drop-down list.');
                $validation->setFormula1(sprintf('"%s"', implode(',', $dropdownOptions)));
                $worksheetNames->getCell($drop_phase1)->setDataValidation(clone $validation);
                $worksheetNames->setCellValue($column . $row, $label->fld_label);
                $worksheetNames->setCellValue($column . ($row + 1), $label->Field_Name);
                $column++;
            }
        }  
         $fileName = $tableSelect . '.xlsx';
            $filePath = storage_path('app/' . $fileName);
        
            $writer->save($filePath);
        
            $headers = [
                'Content-Type' => 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet',
                'Content-Disposition' => 'attachment; filename="' . $fileName . '"',
