Following your error message the issue might be a v-for
without a key
, in order to fix it, you can use a property you have in your array or create an index.
You should replace this the code below on components/datatable/datatable.html
<td v-for="item in props.item.content">
{{ item.content }}
</td>
For this:
<td v-for="(item, index) in props.item.content" :key="index">
{{ item.content }}
</td>
Where an index is created to v-for
and it is used as key
