Horizontal virtual scrolling improves performance by rendering only displayed columns. To enable this feature, set scrolling.columnRenderingMode to "virtual".
You can scroll the component's data horizontally using Shift + Scroll Wheel. Utilize the Home/End keys to jump to the focused row's first/last cells, and Ctrl + Home/Ctrl + End to jump to the first cell of the first row/last cell of the last row.
