Why is the table example from bootstrap-vue not working?

Question

Vue.js

There is an example of a table in table-vue: example
And there is a project where I already insert this example in full: codesandbox
Why doesn't the example work for me?

Answer 1

The bootstrap-vue version is outdated. Yes, and vue itself is also needed differently. Update them.
Well, or change the slot syntax to the old one. That is, for example, instead
of
slot="index" slot-scope="data"
