i added custom columns in Sales Order Grid successfully, but when i export data in CSV file the custom column blanked

namespace Vender\Module\Ui\Component\Listing\Column;

use \Magento\Sales\Api\OrderRepositoryInterface;
use \Magento\Framework\View\Element\UiComponent\ContextInterface;
use \Magento\Framework\View\Element\UiComponentFactory;
use \Magento\Ui\Component\Listing\Columns\Column;
use \Magento\Framework\Api\SearchCriteriaBuilder;

class CGST extends Column
    protected $_orderRepository;
    protected $_searchCriteria;

    public function __construct(ContextInterface $context, UiComponentFactory $uiComponentFactory, OrderRepositoryInterface $orderRepository, SearchCriteriaBuilder $criteria, array $components = [], array $data = [])
        $this->_orderRepository = $orderRepository;
        $this->_searchCriteria  = $criteria;
        parent::__construct($context, $uiComponentFactory, $components, $data);

    public function prepareDataSource(array $dataSource)
        if (isset($dataSource['data']['items'])) {
            foreach ($dataSource['data']['items'] as & $item) {

                $order  = $this->_orderRepository->get($item["entity_id"]);
                $export_status = $order->getData("cgst");

                $item[$this->getData('name')] = $export_status;

        return $dataSource;

and here is my xml file

<?xml version="1.0" encoding="UTF-8"?>
<listing xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">
    <columns name="sales_order_columns">
        <column name="cgst" class="Vender\Module\Ui\Component\Listing\Column\CGST">
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="visible" xsi:type="string">true</item>
                    <item name="label" xsi:type="string" translate="true">CGST</item>

For export functionality /vendor/magento/module-ui/Model/Export/ is responsible to export data. so you need to look in to this core file and override below two file and customize as per your requirement.




Then, you need to add custom code on function getCsvFile()

And you need to add SKU column to sales order grid to render data.
