我正在尝试使用 Vue 和 PrimeVue 显示数据表。它不加载数据，甚至也不显示表格。它在控制台上给出此警告消息：
[Vue warn]: Component is missing template or render function.

app.js：
const { createApp, ref } = Vue
const App = {
setup() {
const products = ref([])
return { products }
},
components: {
"p-column": primevue.column,
"p-datatable": primevue.datatable
}}
createApp(App).use(primevue.config.default).mount("#app")
我尝试使用填充数组和空数组，但两者都不起作用。什么可能导致此错误？
如果使用CDN，则必须单独加载组件（参见docs），因此对于datatable和column，需要添加：
<script src="https://unpkg.com/primevue/datatable/datatable.min.js"></script>
<script src="https://unpkg.com/primevue/column/column.min.js"></script>
这是一个片段：
const { createApp, ref } = Vue
const App = {
setup() {
const products = ref([])
return {
products
}
},
components: {
"p-column": primevue.column,
"p-datatable": primevue.datatable
}
}
const app = createApp(App)
.use(primevue.config.default)
.mount("#app")
