        <el-button
          size="small"
          @click="handleEdit(scope.$index, scope.row)">Edit</el-button>
        <el-button
          size="small"
          type="danger"
          @click="handleDelete(scope.$index, scope.row)">Delete</el-button>
      </template>
    </el-table-column>
.........
</template>
<script>
    import moment from 'moment';
    import Posts from '../api/posts/posts';

    export default {
        data() {
            return {
                posts: [],
            };
        },
