Description
What problem does this feature solve?
图1是目前的效果
图2，3，4是excel的效果
希望能否额外给hoverMode加个参数，变成excel这样的效果，不受其他合并单元格的影响，只占据鼠标所在的单元格整行整列高亮效果，现在遇到合并单元格时效果像多了个痘，用户体验不好，有点乱不美观，
What does the proposed API look like?
希望hover高亮和鼠标点击单元格高亮效果和excel一致，查看excel效果在视图->高亮行列

Research direction
Start by locating the hoverMode implementation and the code that determines highlighting for merged cells. Compare the current behavior with the Excel examples in the issue and define how the optional configuration should affect hover and click highlighting. Done means merged cells no longer distort the selected row and column when the new behavior is enabled.
