Vue Tables 2 - Custom filters

Question

I'm trying to use this https://github.com/matfish2/vue-tables-2 with Vue 2.1.8.

And it's working perfectly BUT I need to use custom filters to format some fields based on their value etc.

In options I have this:

customFilters: [
{
  name:'count',
  callback: function(row, query) {
    console.log('see me?'); // Not firing this
    return row.count[0] == query;
}
}
]

In the docs it says I have to do this:

Using the event bus:

Event.$emit('vue-tables.filter::count', query);

But I have no idea where to put this? I tried many places. For example in my axios success callback but nothing.

I guess this is very basic and I should know this but I don't. So if someone could tell me where to put that event bus staff would be awesome!

The docs could be describing this better. It's a bit difficult to understand.

You need to import the named export Event of vue-tables-2, so you have the event bus of the table and emit the custom event in your custom click handler.

In the demo it's available on global object. In ES6 you'll import it as described in the docs with import {ServerTable, ClientTable, Event} from 'vue-tables-2';

Please have a look at the alphabet filter demo below or in this fiddle.

The demo is similar to the vue-tables-1 demo fiddle that you can find here.

// Vue.use(VueTables)
const ClientTable = VueTables.ClientTable
const Event = VueTables.Event // import eventbus

console.log(VueTables);
Vue.use(ClientTable)

new Vue({
  el: "#people",
  methods: {
    applyFilter(letter) {
      this.selectedLetter = letter;
      Event.$emit('vue-tables.filter::alphabet', letter);
    }
  },
  data() {
    return {
      letters: ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z'],
      selectedLetter: '',
      columns: ['id', 'name', 'age'],
      tableData: [{
        id: 1,
        name: "John",
        age: "20"
      }, {
        id: 2,
        name: "Jane",
        age: "24"
      }, {
        id: 3,
        name: "Susan",
        age: "16"
      }, {
        id: 4,
        name: "Chris",
        age: "55"
      }, {
        id: 5,
        name: "Dan",
        age: "40"
      }],
      options: {
        // see the options API
        customFilters: [{
          name: 'alphabet',
          callback: function(row, query) {
            return row.name[0] == query;
          }
        }]
      }
    }
  }
});
