      <td>
        <b-button variant="dark" :to=" '/orders/' + order">Detail</b-button>

<script>
import axios from "axios";
export default {
  name: 'OrderListing',
  props: {
    order: Object
  },
  data: function() {
    return {
      orders: []
    }
  },
  mounted() {
    axios.get("https://euas.person.ee/user/orders")
      .then(response => {
        this.orders = response.data;
      });
  }

据我了解，您正在寻找这样的东西：

<div v-for="order in orders" :key="order.id">
     <div v-for="item in order.items" :key="item.productId">
         <img :src="item.optionImage" class="option-image" />
     </div>
 </div>
