描述

Hi,

There is an issue with MultiSelectCells functionality of CellNav module. I can select multiple cells using CTRL + cell selection, however after scrolling the grid (up or down) the multi-selection gets cleared and only the first cell from the collection remains highlighted.

It can be reproduced in the CellNav tutorial: http://ui-grid.info/docs/#/tutorial/202_cellnav

  1. Select multiple cells using CTRL + selection
  2. Scroll the grid up/down
  3. Observe the selections disappearing.

研究方向
The bug is that multi cell selection clears after scrolling. The issue likely lies in the CellNav module's scroll event handling. Examine the 'cellnav.js' file for selection state management during scroll. The fix should preserve the selected cells set when rows are re rendered or viewport changes. No comments or PRs exist, so the exact cause needs investigation.
