Hello Magento's,
How we can add column to Sales order history content into customer account.
can anyone help me please?
You need to copy:
magento2Root/vendor/magento/module-sales/view/frontend/templates/order/history.phtml
to
app/design/frontend/{Package}/{theme}/Magento_Sales/templates/order/history.phtml
You can add custom column at above file where needed.
