我将此包https://github.com/yajra/laravel-datatables用于Laravel 5.5 我在浏览器选项卡而不是表格上得到以下响应。没有数据表功能，页面将完全加载静态内容。谁能指出我片段中缺少的内容？

您在/product中用相同的URL get和相同的方法web.php设置了两个动作。在这种情况下，Laravel使用最后一个ProductController@getdata，因此您在浏览器中将得到json而不是html。

只需更改ajax的网址，如下所示：

Route::get('product-data', 'ProductController@getdata')->name('product.getdata');

也将route('product/getdata')替换为route('product.getdata');

为什么我的数据表不能正常工作？
