How enabled sorting without fields object

[Eliophot]

Hello,
Is it possible to activate sorting other than in the fields object?
I don't know in advance the number of fields...
Perhaps in the slot :

<template #head()="data">

Thanks

I don't believe it's possible without passing in a fields array.

Assuming you're currently utilizing the auto generated fields by only passing in items.
You could utilize the same method to generate a fields array which you can then pass to your table.

<b-table :items="items" :fields="fields" />

{
  computed: {
    fields() {
      if(this.items.length === 0) return [];
      const item = this.items[0];
      return Object.keys(item).map(field => ({ key: field, sortable: true }));
    }
  },
  data() {
    return {
      items: []
    }
  }
}

The above example will generate a field array based on the first object in your items array.
It will then map the keys and add sortable: true to all the fields.

This should create fields and enable sorting for all fields automatically based on your data.
