如何打破引导表内的行？

Question

我正在尝试在表内的数组上创建.join()。预期结果是每辆车（在下面的示例中）都排在一行。

我尝试过使用.join("\r\n") 和.join("<br />")，但它不起作用。我错过了什么？

new Vue({
  el: "#table",
  data() {
    return {
      items: [
        { firstname: "John", lastname: "Doe", cars: ["Ferrari", "Tesla"] },
        { firstname: "Jane", lastname: "Doe", cars: ["BMW", "Civic"] },
        { firstname: "Jack", lastname: "Doo", cars: ["Corsa", "Golf"] },
        { firstname: "Julie", lastname: "Doo", cars: ["Fiesta", "Brasilia"] }
      ],
      fields: [
        { key: "firstname", label: "First name" },
        { key: "lastname", label: "Last name" },
        { key: "cars", label: "Cars" }
      ]
    };
  },
  methods: {
    join() {
      for (let item of this.items) {
        item.cars = item.cars.join("<br />")
      }
    }
  }
});

<div id="table">
  <b-button @click="join">Join Array</b-button>
  <b-table :fields="fields" :items="items" />
</div>

上面的 sn-p 相同，但在 CodePen。

您看到的问题是内容没有被解释，因此它显示为文本。要对此进行调整，请使用cell(key) 插槽。然后在槽内，使用v-html将字符串解释为html。

new Vue({
  el: "#table",
  data() {
    return {
      items: [
        { firstname: "John", lastname: "Doe", cars: ["Ferrari", "Tesla"] },
        { firstname: "Jane", lastname: "Doe", cars: ["BMW", "Civic"] },
        { firstname: "Jack", lastname: "Doo", cars: ["Corsa", "Golf"] },
        { firstname: "Julie", lastname: "Doo", cars: ["Fiesta", "Brasilia"] }
      ],
      fields: [
        { key: "firstname", label: "First name" },
        { key: "lastname", label: "Last name" },
        { key: "cars", label: "Cars" }
      ]
    };
  },
  methods: {
    join() {
      for (let item of this.items) {
        item.cars = item.cars.join("<br />")
      }
    }
  }
});

<div id="table">
  <b-button @click="join">Join Array</b-button>
  <b-table :fields="fields" :items="items">
      <template #cell(cars)="data">
        <span v-html="data.value"></span>
      </template>
  </b-table>
</div>

假设您希望它始终位于单独的行上（不仅是在单击示例中的按钮之后），那么您可以使用<b-table> 提供的插槽来自定义列的内容，并使用简单的v-for 将每个元素呈现在它自己的 <div> 中。

new Vue({
  el: "#table",
  data() {
    return {
      items: [
        { firstname: "John", lastname: "Doe", cars: ["Ferrari", "Tesla"] },
        { firstname: "Jane", lastname: "Doe", cars: ["BMW", "Civic"] },
        { firstname: "Jack", lastname: "Doo", cars: ["Corsa", "Golf"] },
        { firstname: "Julie", lastname: "Doo", cars: ["Fiesta", "Brasilia"] }
      ],
      fields: [
        { key: "firstname", label: "First name" },
        { key: "lastname", label: "Last name" },
        { key: "cars", label: "Cars" }
      ]
    };
  }
});

<div id="table">
  <b-table :fields="fields" :items="items">
    <template #cell(cars)="{ value }">
      <div v-for="car in value" :key="car">
        {{ car }}
      </div>
    </template>
  </b-table>
</div>
