我是magento 2的新手，我希望将2个现有表加入一点计算，然后将其显示在管理网格中。
我已经通过一些教程进行了以下一些调整，但是并没有呈现网格，这是做这样的事情的正确方法还是有一些更简单的方法？
我基本上想做的是获取总库存量，减去待定订单，然后减去待定订单后得到实际库存量。
Controller / Adminhtml / Index / Index.php
<?php
namespace Test\StockChecker\Controller\Adminhtml\Index;
class Index extends \Magento\Backend\App\Action
{
protected $resultPageFactory = false;
public function __construct(
\Magento\Backend\App\Action\Context $context,
\Magento\Framework\View\Result\PageFactory $resultPageFactory
)
{
parent::__construct($context);
$this->resultPageFactory = $resultPageFactory;
}
public function execute()
{
try{
$resultPage = $this->resultPageFactory->create();
$resultPage->getConfig()->getTitle()->prepend((__('Stock Status')));
}
catch(Exception $e){
$this->messageManager->addError($e);
}
return $resultPage;
}
}
