Custom Kendo Vue Grid Wrapper Column Template Using kendo-grid columns Attribute - vue.js

Question

I have the following template that I would like to use to render the contents of a Kendo grid wrapper cell:
<template>
<span>
Template Rendered: {{ templateArgs.name }}
</span>
</template>
<script>
export default {
name: 'template1',
data () {
return {
templateArgs: {}
}
}
}
</script>
I am able to do this using kendo-grid-column elements as follows:
<template>
<div>
<kendo-grid :data-source="datasource">
<kendo-grid-column field="name" title="Name" :template="itemTemplate"></kendo-grid-column>
</kendo-grid>
</div>
</template>
<script>
import Vue from 'vue'
import { Grid, GridColumn } from '#progress/kendo-grid-vue-wrapper'
import Template from './Template.vue'
var itemTemplate = Vue.component(Template.name, Template)
export default {
name: 'HelloWorld',
components: {
'kendo-grid': Grid,
'kendo-grid-column': GridColumn
},
methods: {
itemTemplate: function (e) {
return {
template: itemTemplate,
templateArgs: e
}
}
},
data () {
return {
datasource: [ { name: "Jane Doe" }, { name: "John Doe" } ]
}
}
}
</script>
I would like to use the kendo-grid columns attribute instead, as follows:
<template>
<div>
<kendo-grid :data-source="datasource" :columns="columns">
</kendo-grid>
</div>
</template>
<script>
import Vue from 'vue'
import { Grid, GridColumn } from '#progress/kendo-grid-vue-wrapper'
import Template from './Template.vue'
var itemTemplate = Vue.component(Template.name, Template)
export default {
name: 'HelloWorld',
components: {
'kendo-grid': Grid,
'kendo-grid-column': GridColumn
},
methods: {
itemTemplate: function (e) {
return {
template: itemTemplate,
templateArgs: e
}
}
},
data () {
return {
columns: [{ field: "name", title: "Name", template: this.itemTemplate }],
datasource: [ { name: "Jane Doe" }, { name: "John Doe" } ]
}
}
}
</script>
Something is wrong with the code in the second case, though. Instead of rendering the cells using the template, I am getting [object Object] as the cell contents. What should I do in order to fix this?

Using the columns property when using custom render templates is not supported by the Vue grid wrapper. Something similar can be done with a native grid, however.
