Breaking rows in Bootstrap tables: A guide to implementing row breaking in Bootstrap tables

Question

I'm trying to create a .join() on an array within a table. The expected result is that each vehicle (in the example below) is in a row.

I have tried using .join("\r\n") and .join("<br />") but it doesn't work. What did I miss?

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>

Same code snippet as above, but on CodePen.

Assuming you want it to always be on a separate row (and not just after clicking the button as in the example), then you can customize it using the slot provided by <b-table> content of the column, and uses a simple v-for to render each element in its own <div>.

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" }
      ]
    };
  }
});

The problem you are seeing is that the content is not interpreted, so it is displayed as text. To adjust this, use the cell(key) slot. Then in the slot, use v-html to interpret the string as 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("
")
      }
    }
  }
});
