Vue - how to pass down slots inside wrapper component?

So I've created a simple wrapper component with template like:

<wrapper>
   <b-table v-bind="$attrs" v-on="$listeners"></b-table>
</wrapper>

using $attrs and $listeners to pass down props and events.
Works fine, but how can the wrapper proxy the <b-table> named slots to the child?

Vue 3

Same as the Vue 2.6 example below except:

• $listeners has been merged into $attrs so v-on="$listeners" is no longer necessary. See the migration guide.
• $scopedSlots is now just $slots. See migration guide.

<template v-for="(_, slot) of $slots" v-slot:[slot]="scope || {}"><slot :name="slot" v-bind="scope"/></template>

Vue 2.6 (v-slot syntax)

All ordinary slots will be added to scoped slots, so you only need to do this:

<wrapper>
  <b-table v-bind="$attrs" v-on="$listeners">
    <template v-for="(_, slot) of $scopedSlots" v-slot:[slot]="scope"><slot :name="slot" v-bind="scope"/></template>
  </b-table>
</wrapper>

Vue 2.5

See Paul's answer.

Original answer

You need to specify the slots like this:

<wrapper>
  <b-table v-bind="$attrs" v-on="$listeners">
    <!-- Pass on the default slot -->
    <slot/>

    <!-- Pass on any named slots -->
    <slot name="foo" slot="foo"/>
    <slot name="bar" slot="bar"/>

    <!-- Pass on any scoped slots -->
    <template slot="baz" slot-scope="scope"><slot name="baz" v-bind="scope"/></template>
  </b-table>
</wrapper>

Render function

render(h) {
  const children = Object.keys(this.$slots).map(slot => h('template', { slot }, this.$slots[slot]))
  return h('wrapper', [
    h('b-table', {
      attrs: this.$attrs,
      on: this.$listeners,
      scopedSlots: this.$scopedSlots,
    }, children)
  ])
}

You probably also want to set inheritAttrs to false on the component.
