ag grid tree - 如何在 rowData 更新后保持树状态（合同级别）？
aggrid tree - how to keep tree state (contracted levels) after rowData updated?
有没有办法在 rowData 更新后保持树状态？不幸的是，每次我刷新数据并更新 rowData 时，状态都会恢复为默认值（折叠）。
经过大量搜索，我在aggrid网站上找到了答案：
https://www.ag-grid.com/javascript-grid-grouping/#keeping-group-state
"When you set new data into the group by default all the group open/closed states are reset. If you want to keep the original state, then set the property"
rememberGroupStateWhenNewData=true
