Allow for more customisability - New slot for the VDataTable

[DCzajkowski]

Description

Added a scoped slot for adding additional things to the data table's actions footer.

Motivation and Context

It allows for more customisability. Currently, to add anything to the actions footer one needs to remake whole table's footer.

How Has This Been Tested?

Visually

Before

After (gives possibility to append anything)

Markup:

<template>
  <v-data-table
    :headers="headers"
    :items="desserts"
    hide-actions
    class="elevation-1"
  >
    <template slot="items" slot-scope="props">
      <td>{{ props.item.name }}</td>
      <td class="text-xs-right">{{ props.item.calories }}</td>
      <td class="text-xs-right">{{ props.item.fat }}</td>
      <td class="text-xs-right">{{ props.item.carbs }}</td>
      <td class="text-xs-right">{{ props.item.protein }}</td>
      <td class="text-xs-right">{{ props.item.iron }}</td>
    </template>

    <!-- What was added -->

    <template slot="actions-extras">
      <v-btn color="green">New</v-btn>
    </template>
    
    <!-- /What was added -->

  </v-data-table>
</template>

<script>
  export default {
    data () {
      return {
        headers: [
          {
            text: 'Dessert (100g serving)',
            align: 'left',
            sortable: false,
            value: 'name'
          },
          { text: 'Calories', value: 'calories' },
          { text: 'Fat (g)', value: 'fat' },
          { text: 'Carbs (g)', value: 'carbs' },
          { text: 'Protein (g)', value: 'protein' },
          { text: 'Iron (%)', value: 'iron' }
        ],
        desserts: [
          {
            value: false,
            name: 'Frozen Yogurt',
            calories: 159,
            fat: 6.0,
            carbs: 24,
            protein: 4.0,
            iron: '1%'
          }
        ]
      }
    }
  }

To make things consistent with the rest of the framework, I think it should probably be named actions-append. And you could add a actions-prepend slot as well.

[DCzajkowski]

Good call. I'll update that today.

[DCzajkowski]

Ok, done :)

[DCzajkowski]

Is there any update on that? 😊
