vue3 多个tab自动切换时只有第一个tab的组件显示

首先有三个tab对应三个组件(BarChart)

const showTab1 = ref(true)
const showTab2 = ref(false)
const showTab3 = ref(false)
const data1 = ref({})
const tab1style = ref(active)
const tab2style = ref()
const tab3style = ref()
cnost tabnidex = ref()

<div class="tab" id="tab">
	<ul>
		<li><a :class="tab1style" @click.stop.prevent="tabClick(1)"
