Can someone tell me what m i missing or doing wrong in here because then i have to add proper functionality to it

<script>
export default {
  data() {
    return {
      itemsPerPage: 5,
        categories: [],
        //actions:"",

        headers: [
         { title: "Category ID", value: "CategoryId" },
        { title: "Category", value: "Category" },
        { title: "Actions", value: "Actions", sortable: false },
      ],
    };
  },

Answer 1

It says you are using Vue 3 in the tags, which means you are using Vuetify 3. In the current version of VDataTable, use key instead of value in the header declaration:

headers: [
  { title: "Category ID", key: "CategoryId" },
  { title: "Category", key: "Category" },
  { title: "Actions", key: "Actions", sortable: false },
],

Also, the #item.<column name> slot name has to match the key, which would make it #item.Category (upper-cased "category"), not #item.category. And the item in the slot props is the internal table item, not the entry from the array you passed in. But it can be accessed through the raw property. So the slot should be:

<template #item.Category="{ item }">
  <strong>{{ item.raw.category }}</strong>
</template>

With these changes, your table renders in the playground
