PHPExcel 公式在 HTML 中不起作用

Question

如果我使用 Excel2007 writer，它可以工作，但是当我将它写成 HTML 时，公式根本不起作用。

这是我的代码。它在 CodeIgniter 中

function monthly_plan(){
    $data['page_title'] = 'Monthly Plan';
    $data['main'] = 'reports/monthly_plan';
    $data['lines'] = $this->line_model->getLines();

    if($this->input->post('generate')){
        $m = $this->input->post('month');
        $pid = $this->input->post('process_id');
        $date_start = date('Y-'.$m.'-01');
        $date_end = date('Y-'.$m.'-t');
        $last_month = date('Y-m-d', strtotime($date_start.' -1 day'));
        $date_max = date('t');
        $schedules = $this->getScheduleInProcess($pid, $date_start, $date_end, true, true);
        $process = $this->process_model->getProcess($pid);

        $separators = []; $item_names = [];

        // EXCEL

        $this->load->library('excel');

        $this->excel->setActiveSheetIndex(0);
        $sheet = $this->excel->getActiveSheet();

        $sheet->setTitle('Planning Bulanan');
        $sheet->setCellValue('A2', 'Process');
        $sheet->setCellValue('B2', $process->process_name);
        $sheet->setCellValue('C2', 'L/M');

        $last_num = 2; // row terakhir
        $last_num_counter = 2; // row terakhir untuk counter

        for($i = 4; $i <= $date_max + 3; $i++){
            $cell = $this->translate_cell($i);
            $sheet->setCellValue($cell.'2', date(($i - 3).'-M'));
        }

        foreach($schedules as $schedule){

            $sheet->setCellValue('B'.$last_num, 'plan prod');
            $sheet->setCellValue('C'.$last_num, '');

            $sheet->setCellValue('A'.(++$last_num), $this->is_lot($route) ? '':$route->efficiency);

}

有人遇到过这个问题吗？我不知道这个问题，请有人拯救我的一天。

解决了这个问题，在 HTML 编写器单元格中应该以大写形式编写，例如 A1，在从 $this->translate_cell($i); 返回的 mycode 中是小写形式；.
