How to draw table with columns in outside of screen?

Hey, when im trying to render table with columns in outside of screen i got on this columns only headers without data
that's my code
https://codesandbox.io/s/vue-virtual-scroller-xs7hb?fontsize=14

i can fix it by adding

```
.vue-recycle-scroller__item-wrapper,
.vue-recycle-scroller__slot {
min-width: 3222px;
}
```

but after this i will have many empty space in horizontal scroll

also i tried to add
`overflow-x: auto;`
its fixed it, but with scrolling it will move only data (without headers)
