Get the contents of the selected table by selecting multiple tables in element-ui

this is the recharge list I have made. I want to select multiple recharge orders and click the next step to go to another page. I will add the recharge amount of the selected list to the total amount of the next page. How can I ask the boss to tell me?


get two items separately and add them together.

html
 <el-table @section-change="handler">
    ///
 </el-table>
js
methods:{
    handler(select){
        console.log(select)// 
    }
}
