我是Apache POI库的初学者.

在VBA中,我知道我可以使用以下代码选择并加粗整个工作表

Dim ws As Worksheet
Set ws = ThisWorkbook.Sheets(1)
ws.Cells.Font.Bold = True

我是否可以通过使用Apache POI库进行编码来了解如何选择和加粗整个工作表？

谢谢

以下是我在Laravel 5.2中实现主 - 详细信息页面的两个模型,刀片页面和控制器.我想知道如何将详细信息部分更新回数据库.

1)主模型

namespace App;

use Illuminate\Database\Eloquent\Model;

class Order  extends Model
{
    protected $fillable = [
        'id',
        'name',
        'created_at',
        'updated_at'
    ];

    public function detail()
    {
        return $this->hasMany('App\OrderDetail','fid','id');
    }   



    public function getDetailCountAttribute()
    {
        return $this->hasMany('App\OrderDetail','fid','id')->count();
    }       


    public static function boot()
    {
        parent::boot();    

        // cause a delete of a product to cascade to children so they are also deleted
        static::deleted(function($order)
        {
            $order->detail()->delete();
        });
    }    
}

2)细节模型

namespace App;

use Illuminate\Database\Eloquent\Model;

class OrderDetail extends Model
{
    protected $fillable = [
        'id', …
