How to expand and collapse multiple rows in table using java script?

All rows are collapsed by default. Assign an array of keys to the expandedRowKeys property to expand specific rows initially. If a to-be-expanded row lies deep in the hierarchy, make sure to include keys of all its parent rows as well. Set the autoExpandAll property to true if all rows should be expanded initially.
