我想在Qtable中只选择一行关键字字段(而不是整行数据(到目前为止，我可以在使用行键时切换复选框this.selected=[{"name"："Eclair"}]但我预计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数据
然后
单击按钮，注意字符串化的数据并不是整行。代码笔https://codepen.io/jniumata/pen/YzVWoQO
因此，我的问题是，如何通过编程只使用行键字段选择一行，并将整行数据放入数组中。(注意：我不想传递整个对象，只需要传递行键(
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)',
