Question

I have a simple data table using Vuetify data table. One of the column is a createdOn (date time), I want to format it. How can I do it ?

<template>
   <v-layout>
      <v-data-table :headers="headers" :items="logs">
      </v-data-table>
   <v-layout>
</template>
<script>
      headers: [
        { text: "Time", value: "createdOn", dataType: "Date" },
        { text: "Event Source", value: "eventSourceName" },
        { text: "Event Details", value: "eventDetails" },
        { text: "User", value: "user" }
      ],
      items: [],
</script>

You should use a custom row cell :

<v-data-table :headers="headers" :items="logs">
         <template v-slot:item.createdOn="{ item }">
           <span>{{new Date(item.createdOn).toLocaleString()}}</span>
         </template>
      </v-data-table>
