一对多反向关联 

news.user_id 与user.id关联

模型层 newmodel

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class NewModel extends Model
{
    protected $table = "news";

    public function users()
    {
        return $this->belongsTo('App\Models\UsersModel','user_id');
    }
}

　　模型层 usermodel

class UsersModel extends Model
{
    protected $table = "users";

}

　　控制器

  $grid = new Grid(new NewModel());

        $grid->column('id', __('Id'));
        $grid->column('title', __('Title'));
        $grid->column('content', __('Content'));
        $grid->column('user_id', __('User id'));
        $grid->column('users.id',__("作者id"));
        $grid->column('users.name',__('作者'));
        $grid->column('created_at', __('Created at'));
        $grid->column('updated_at', __('Updated at'));

        return $grid;
