只需要添加一行代码：

@row-click="rowClick">

在el-table中添加，如：

<el-table
            :data="tableData5"
            style="width: 100%"
            row-key="id"
            :expand-row-keys="expands"
            @row-click="rowClick">

js

rowClick(row, event, column) {
   
               
                 console.log(row,event,column)
        }
