Virtual Scrolling is an efficient way to render large amount data. Usage is similar to regular scrolling with the addition of <i>virtualScrollerOptions</i> property to define a fixed <i>itemSize</i>. Internally,
<PrimeVueNuxtLink to="/virtualscroller">VirtualScroller</PrimeVueNuxtLink> component is utilized so refer to the API of VirtualScroller for more information about the available options.

<p>In this example, <strong>100000</strong> preloaded records are rendered by the Table.</p>
