我相信对我想要实现的目标有更好的解释,所以请自由编辑。
假设我有一个菜单,其中列出了水果及其价格。
我想显示一个矩形,它将在项目之间进行迭代(假设它在每个项目上停留2秒钟)。另外,我想暂时使当前带有矩形的项目的字体加粗。
哪个组件或我应该在Vuetify中寻找什么?

Menu.vue
<template>
<v-simple-table>
<template v-slot:default>
<tbody>
<tr v-for="item in menuItems" :key="item.name">
<td>{{ item.name }}</td>
<td>{{ item.price }}</td>
</tr>
</tbody>
</template>
</v-simple-table>
</template>
<script>
export default {
data() {
return {
menuItems: {
1: {
name: "Apple",
price: 20
},
2: {
name: "Orange",
price: 21
},
3: {
name: "Pear",
price: 22
},
4: {
name: "Grape",
price: 23
}
}
};
}
};
</script>
是,可以突出显示序列中的行
