如何在管理产品编辑页面Magento2中创建选项卡和网格

Question

我在这里使用事件观察者＆＃34; controller_action_layout_render_before_adminhtml_catalog_product_edit＆＃34;在产品选项卡中呈现自定义模块网格但不起作用。

这里我创建了Grid.php文件。

请帮忙。

1. 我创建了以下观察文件。 应用程序/代码/命名空间/模块/观测/ AddStockMovementsTab.php 尝试在此文件中编写代码。

2. 应用程序/代码/命名空间/模块/块/ Adminhtml /观看/ Grid.php
