Select products sku in shortcode

for that, u have to customize using filter hook.
Check hook list.

Sorry, I could not find it in the documentation. Can you point where can I find it? Or even give some example about this feature? This feature can be used only in the premium version?

Check this one https://wooproducttable.com/plugin-api/wpto_table_query_args/

Hope you can understand how to use this filter for your attributes
