Laravel，如何基于此代码修改/编辑Excel？

Question

我在控制器中有一个工作代码，如下所示，问题是当我要编辑其内容时，它无法保存。

控制器

$rows = Excel::load($file_path, function($reader) use ($column_number)
{
    $reader->takeColumns($column_number);
    $reader->noHeading();

})->get();

$rows = $rows->toArray();

查看内容

dump($rows[0][0]); // this will display A1 cell and it is working fine

但是当我尝试这样做

$rows[0][0] = "Test"; // this will not write the cell A1
dump($rows); // but it will display as shown in picture below

通过工作表索引加载文件并附加值

$download_file_name = 'DataFile';
 Excel::selectSheetsByIndex(1)->load($file_path, function($reader) use () {
    $reader->sheet('Sheet1', function($sheet) use () {
        //if you want to add value append single value
        $sheet->SetCellValue("A7", "Exporter");
        //if want to append row
        $sheet->appendRow($dispColArray);                  
                     });
}, 'UTF-8')->setFilename($download_file_name)->download('xls');

您还可以将以下功能用于图纸样式

1. 用于工作表样式

   $sheet->setStyle(array(
       'font' => array(
           'name' => 'Calibri',
           'size' => 9,
           'background' => '#ffffff'
       )
   ));
   

2. 合并单元格和设计

   $sheet->mergeCells('A1:D4');
   $sheet->cells('A1:D4', function($cells) {
       $cells->setBackground('#ffffff');
   
   });

您可以在Excel Load中修改值。

$rows = Excel::load($file_path, function($reader)
{
    $reader->sheet('sheet1', function($sheet){
        $sheet->cells('E4', function($cell) {
            $cell->setValue('my value');
        });
    });     

})->store('xls');
