问题 Initially, all rows will have the same height of 50. When a cell is focused,if it has more content and requires more height, I need to increase the height of that particular cell. If that is not possible, atleast that entire particular row's height has to be increased. The remaining rows should not get effected. 回答1: I would make use of rowSelection api particularly the selected property of each rowNode . You can define getRowHeight in html [getRowHeight]="getRowHeight" and (selectionChanged)
