select - 如何以编程方式正确选择 Quasar 中 Qtable 中的行

Question

到目前为止，我想在 Qtable 中仅使用行键字段（而不是整个行数据）选择一行，当我使用行键 this.selected = [{"name": "Eclair"}] 但我希望整个行数据会填充到所选对象中，但事实并非如此。转到下面的代码笔，首先尝试单击复选框并注意屏幕底部的字符串化数据，

然后

点击按钮，注意字符串化的数据不是整行。代码笔 https://codepen.io/jniumata/pen/YzVWoQO

所以我的问题是，如何以编程方式选择仅包含行键字段的行，并将整个行数据放入数组中。（注意：我不想传递整个对象，只传递 row-key ）

new Vue({
  el: '#q-app',
  methods: {
    onChangeSelect (details) {
      console.log('details: ', details)
      // parse details and make a request.... 
    },
    testMethod () {
      if(this.selected.length > 0) {
        this.selected = [];
      } else {
        this.selected = [{"name": "Eclair"}];  
      }
      
    }
  },
  data () {
    return {
      selected: [],
      columns: [
        {
          name: 'desc',
          required: true,
          label: 'Dessert (100g serving)',
          align: 'left',
          field: row => row.name,
          format: val => `${val}`,
          sortable: true
        },
        { name: 'calories', align: 'center', label: 'Calories', field: 'calories', sortable: true },
