What is the event in which the table component clicks the expand button in the urgent request for the version of: elementUI (1.x), and can you get it?

as shown in the figure above: the enclosed part is obtained dynamically after clicking the expand button, so what is the time when the button is clicked? I want to get the expanded data when I click the expand button. I hope the great god can give us some advice. I would appreciate it.
