CRUD show table entries in frontend

I have come to this forum trying to get an answer to what it seems to be the most precious secret of wordpress coding:

Having finished this tutorial successfully,

https://github.com/eduardoarandah/wordpress-crud-example/tree/master/sinetiks-schools

I just want those table entries to be shown in list format and show them individually in detail format, just like wordpress does with its posts. I have navigated lots of hours and encountered some amazing tutorials on other aspects about building a plugin, but nothing on this. Can someone please gimme a hint about this?

Thanks in advance.
