### header-inner-container
The header-inner-container slot is injected into the `div.vue-virtual-collection-container` but appears before cells. Additionally this slot is not removed from the DOM on scroll unlike the cells.

```html
<VirtualCollection
:cellSizeAndPositionGetter="item => { return { width: item.width, height: item.height, x: item.x, y: item.y }}"
:collection="items.items"
:height="items.boxHeight"
:width="items.boxWidth"
:containerHeightSpacer="50"
v-on:scrolled-to-top="scrollTop"
v-on:scrolled-to-bottom="scrollBottom">

<template v-slot:header-inner-container>
<div class="filter-controls">
<!-- inject your component here -->
</div>
</template>

<div slot="cell" slot-scope="props">
{{props.data}}
</div>
</VirtualCollection>
```

### cell
```html
<div slot="cell" slot-scope="yourOwnScope">{{yourOwnScope.data.text}}</div>
