[Vuejs]-Why error is giving for using Vuetify Datatable?

v-slot is not supported until Vue v2.6 as seen here:
https://v2.vuejs.org/v2/guide/components-slots.html

So two options:

• You could either go back to the slot + slot-scope approach with a Vue version less than 2.6.0.

• Or you can upgrade your Vue version to v2.6.0.
