感觉潜得不够深，

对于全局使用来说，简单的方法是使用addField甚至更改 SQL 从一些相关表中添加数据。

public function aroundGetData(\Magento\Catalog\Ui\DataProvider\Product\ProductDataProvider $subject, callable $proceed)
{
    $subject->addField('field', 'alias'); // alias is optional
    $collection = $subject->getCollection(); // Here you have access to all public methods of collection.
    $select = $collection->getSelect(); // You can do whatever you want with Zend_DB_Select here
    return $proceed();    
}

DataProviderhasaddField和addFiltermethodProduct Collection在幕后使用。
