Is there a way to display customized values on a particular column in a Vuetify table?

Question

Is there a way to display customized values on a particular column in a Vuetify table?

In the column named conditions, I am looking to display the count of rules > details.

Please Note:

The array rules has a property details.length = 2

This is what I have attempted

Here is the code snippet:

headers: [
    { text: 'Priority', value: 'priority', width: '10%' },
    {
        text: 'Name',
        align: 'start',
        sortable: false,
        value: 'name',
        width: '30%'
    },
    { text: 'URL', value: 'url', width: '30%' },
    { text: 'Condition', value: '?????????', width: '20%' },
    { text: '', value: 'data-table-expand', width: '5%' }
],

Any ideas on how I can achieve this?

Answer №1

To obtain new items with the desired property, I suggest using the computed method. Simply adjust the property to fit your requirements.

Alternatively, you can utilize v-slot:item.conditions, as demonstrated in the example provided on this page: https://github.com/vuetifyjs/vuetify/blob/master/packages/docs/src/examples/v-data-table/slot-simple-checkbox.vue

Insights/Recommendations :

Avoid assigning dynamic values in the headers array for column names. Instead, incorporate this in the column data.
To meet this requirement, consider adding the condition value in the mounted lifecycle hook.

Example :

new Vue({
  el: '#app',
  vuetify: new Vuetify(),
  data () {
    return {
      headers: [
        { text: "Priority", value: 'priority' },
      { text: "Name", value: 'name' },
      { text: "URL", value: 'url' },
      { text: "Condition", value: 'condition' }
    ],
      rules: [{
      priority: 1,
      name: "Alpha",
      url: 'https://example.com',
      urlGroup: '',
      condition: ''
    }, {
      priority: 2,
      name: "Beta",
      url: 'https://example.com',
      urlGroup: 'userGroup2',
      condition: ''
    }],
    }
  },
  mounted() {
    const rulesLength = this.rules.length;
    this.rules.forEach((obj) => {
        obj.condition = rulesLength;
    })
  },
  methods: {
    displayURLInfo(index) {
      if (this.rules[index].urlGroup != '') {
         return      this.rules[index].urlGroup
      } else {
        return this.rules[index].url
      }
    }
  }
})
