codeigniter3+PHPspreadsheet實現excel導入導出功能
引入composer依賴包PHPspreadsheet
- 根目錄composer.json文件的require節點加入如下內容，注意json格式規則：
"phpoffice/phpspreadsheet": "*" - 之後需執行 composer update 下載PHPspreadsheet依賴包
添加類庫並use相關類
- 在 application\libraries 目錄下添加名爲 Php_spread_sheet_lib.php 的文件（名稱隨意，注意不要使用PHPspreadsheet，避免不必要的衝突，ci3無命名空間）
- use必要類
use PhpOffice\PhpSpreadsheet\Cell\Coordinate; use PhpOffice\PhpSpreadsheet\Cell\DataType; use PhpOffice\PhpSpreadsheet\IOFactory; use PhpOffice\PhpSpreadsheet\Spreadsheet; use PhpOffice\PhpSpreadsheet\Style\Alignment; use PhpOffice\PhpSpreadsheet\Style\Border; use PhpOffice\PhpSpreadsheet\Style\Color; use PhpOffice\PhpSpreadsheet\Style\Fill; use PhpOffice\PhpSpreadsheet\Style\NumberFormat; use PhpOffice\PhpSpreadsheet\Worksheet\PageSetup; use PhpOffice\PhpSpreadsheet\Reader\Xlsx; use PhpOffice\PhpSpreadsheet\Reader\Xls;
添加導入導出方法

實戰應用
- 這裏把我項目中的調用方法展現出來，讀着只需看與excel相關的有用的（寬高、樣式、合併單元格等）即可，看懂類庫文件就能會用，我這裏也是對它的運用
