你可以在 `created` 生命周期函数中监听 `currentOrderTab` 的变化，在 `currentOrderTab` 变化时切换第二个 `el-tabs` 的选项卡，例如：

<el-tabs v-if="orderInvoiceData.length" class='invoice_list' v-model="currentOrderTab" @tab-click="clickOrderTab"> 
  <el-tab-pane :label="numToStr(order.order_info.order_no)" :name="numToStr(order.order_info.order_no)" :key="order.order_info.order_no" v-for="order in orderInvoiceData"> 
    <el-tabs v-if="!order.order_info.is_error" tab-position="left" style="height:calc(100% - 96px);" v-model="currentInvoiceTab"> 
      <el-tab-pane :label="invoice.invoice_info.label" :key="invoice.invoice_info.label" :name="invoice.invoice_info.name" v-for='(invoice, index) in order.invoiceList'> 
      </el-tab-pane> 
    </el-tabs> 
  </el-tab-pane> 
</el-tabs>

created() {
  // 监听 currentOrderTab 的变化
  this.$watch('currentOrderTab', (newVal) => {
    // 找到对应的发票标签页名称
    const invoiceName = this.orderInvoiceData.find(order => numToStr(order.order_info.order_no) === newVal).invoiceList[0].invoice_info.name;
    // 切换第二个 el-tabs 的选项卡为对应的发票标签页
    this.currentInvoiceTab = invoiceName;
  });
}

这样，当你点击第一个 `el-tabs` 的选项卡时，就会自动触发对应的发票标签页。
