this my json

[
    {
      "id":"1",
      "name": "KINTIL",
      "desc": "Kintil is good",
      "location": [
        {
        "prov": "Jawa Barat",
        "city": "Bandung"
        },
        {
        "prov": "Banten",
        "city": "Tanggerang"
        }
      ],
      "applied": [

    :items="inovasi" :fields="fields" :current-page="currentPage" :per-page="0" :filter="filter" >
</b-table>

and this my script

import json from "../static/data.json";
export default {
  name: 'tes',
    data() {
    return {
        inovasi:[],
        filter: null,
        fields: [
         {
            key: 'id',
            label: 'id',
            sortable: true
         },
         {
            key: 'name',
            label: 'name',
            sortable: true
         },
         {
            key: 'location',
            label: 'location',
            sortable: true
         },
         {
            key: 'applied',
            label: 'applied',
            sortable: true
         },
         { key: 'actions', label: 'Doc' }
         ],
         currentPage: 0,
         perPage: 5,
         totalItems: 0
      }
  },
  mounted() {
     this.inovasi = json;
  },
  computed:{
  },
  methods: {
  }
}

how to display location and applied , into a single row table ? thanks in advance for those who have answered :)

Solution

You can do it using formatter like

fields: [
   {
      key: 'id',
      label: 'id',
      sortable: true
   },
   {
      key: 'name',
      label: 'name',
      sortable: true
   },
   {
      key: 'location',
      label: 'location',
      sortable: true,
      formatter: (value, key, item) => { 
         return value.map(x => 'prov: ' + x.prov + ' city:' + x.city).join(", ") 
      }
   },
   {
      key: 'applied',
      label: 'applied',
      sortable: true,
      formatter: (value, key, item) => { 
         return value.map(x => x.item_name).join(", ") 
      }
   },
   { key: 'actions', label: 'Doc' }
],

It will show for the location column this: prov: Jawa Barat city:Bandung, prov: Banten city:Tanggerang and for the applied column this: galian, timbunan
