React Virtualized with Custom Table Component

Question

For my company's react web app, we are doing a single request (non-paginated) that can yield tens of thousands of results. These results are to be rendered on a Table and, given its length, rendering can become sluggish. I was hoping to use something like react-virtualized. However, it seems that react-virtualized's functionality can only be applied to its Table component. Unfortunately, I have to use my company's custom Table (common component).

Is there another non-complex solution that anyone is aware of that would allow performance benefits, such as those seen in react-virtualized's Table, while using a custom Table component? Updating the BE to be paginated so that I could do something like infinite-scroll is probably a non-starter.
