Install numeral.js:

npm install numeral --save  

Define the custom filter:

<script>

  var numeral = require("numeral");



  Vue.filter("formatNumber", function (value) {

    return numeral(value).format("0,0"); // displaying other groupings/separators is possible, look at the docs

  });



  export default

  {

    ...

  } 

</script>

Use it:

<tr v-for="(item, key, index) in tableRows">

  <td>{{item.integerValue | formatNumber}}</td>

</tr>
