I have created a custom product tab by this tutorial.
<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
<body>
<referenceBlock name="product.info.details">
<block class="Magento\Catalog\Block\Product\View" name="test.tab" template="Cloudways_Mymodule::custom_tab.phtml" group="detailed_info" >
<arguments>
<argument translate="true" name="title" xsi:type="string">Custom Tab</argument>
</arguments>
</block>
</referenceBlock>
</body>
</page>
I have placed the above code in app/code/Cloudways/Mymodule/view/frontend/layout/catalog_product_view.xml
and created a template in app/code/Cloudways/Mymodule/view/frontend/templates
which works fine and create one table on product details page.
What if I have to add more than one tab. How should I write the XML?
I have tried these variations but didn't work:
