Sorting tables in Vue.js with Buefy components for a user-friendly experience

In my current project, I am utilizing Vue.js. The majority of the tables I am working with use Buefy's built-in sorting feature, which I find to be the simplest solution. You can find more details in the documentation here:

<template>
    <section>
        <b-table default-sort="user.first_name">
            <template slot-scope="props">
                <b-table-column field="id" label="ID" sortable>
                </b-table-column>

                <b-table-column field="user.first_name" label="First Name">                   </b-table-column>

                <b-table-column field="user.last_name" label="Last Name">
                </b-table-column>

                <b-table-column field="date" label="Date">
                </b-table-column>
            </template>
        </b-table>
    </section>
</template>

However, there is one component in the project that uses a traditional HTML table structure. The data rows are displayed within a Slot component as shown below:

<template>
  <table class="classname">
    <thead>
      <tr>
        <th>Header 1</th>
        <th>Header 2</th>
        <th>Header 3</th>
      </tr>
    </thead>
    <tbody>
      <slot></slot>
    </tbody>
  </table>
</template>

The parent component of the above example looks something like this (examplecomponent being the component where the HTML table is generated):

<div class="grid">
  <examplecomponent :class="exampleclass">
    <template v-for="(row, index) in filteredList">
      <othercomponent></othercomponent>
      <othercomponenttwo></othercomponenttwo>
    </template>
  </examplecomponent>
</div>

Given this setup, my question is how to best handle sorting the data. I attempted to switch the HTML table to use Buefy's b-table but faced challenges. I suspect that adjustments need to be made in the parent component. While the HTML table file has no imports, the parent component has all necessary information accessible.

As a relatively new programmer, I would greatly appreciate a detailed explanation in simple terms, as if explaining to a young child.

Answer №1

After some time, I managed to figure out the solution to my own question.

To make things easier, you can emit the click in the element like this (within a normal HTML table, as a child component):

<template>
  <table>
    <tr>
      <th @click="$emit('sort', {column: 'Name', isAsc: !isAsc})">Name</th>
      <th> ... </th>
    </tr>
  </table>
</template>

props: {
  isAsc: Boolean,
  sortedBy: String
}

In the parent component, something like this should be added:

<child-component-name @sort="sortTable" :sortedBy="sortedBy" :isAsc="isAsc" v-if="yourTableSummary"> ... </child-component-name>

components: {
  'child-component-name': NameOfYourComponent
},

data() {
    return {
        isAsc: true,
        sortedBy: 'Name'
        yourTableSummary: {}
    }
},

methods: {
    sortTable({column, isAsc}) {
        // Set isAsc to default if sorted column changes
        if (column != this.sortedBy) {
            isAsc = true
        }

        let sortedList = []
        if (isAsc) {
            sortedList =
                this.yourTableSummary.Rows.sort((a, b) => {
                    return a[column].localeCompare(b[column])
                })
        } else {
            sortedList =
                this.yourTableSummary.Rows.sort((a, b) => {
                    return (a[column].localeCompare(b[column]) * -1 )
                })
        }

        this.yourTableSummary.Rows = [...sortedList]
        this.sortedBy = column
        this.isAsc = isAsc
    },
}
