描述

I have around 650 rows of data I want to render using UI Grid. However, only the first 6 rows show up. If I set virtualizationThreshold='651', the rows all load, but performance is mind-numbingly poor. Is there a solution that allows virtualization when dealing with large data sets? Please help!

研究方向
Investigate the UI Grid virtualization implementation, focusing on the `virtualizationThreshold` option and the row rendering logic in the `ui grid virtualization` directive. Look at the source code in `src/features/virtualization/` to understand how rows are rendered and why only a subset appears without virtualization. Examine comments in the issue for proposed solutions or workarounds, and consider testing performance improvements with large datasets.
