I want to get three values at the same time in @ selection-change :

• dynaRef (scope.row) , subset el-table reference for checkbox Simulation radio one line must be selected
• scope.row , the data of the expanded row in the parent table, which is used to save the default selected item
• selection , subset el-table selected
• also modify the data in this (current vm instance) according to selection
.

find the custom parameter passing method through search (p)=>fn(p, "1permission, 2)
but this method has a drawback. This pointing is no longer the original vm instance. How to solve this problem?

<el-table :data="grid.data" :border="true" :stripe="true" @expand-change="expandChange">
    <el-table-column fixed type="expand" width="50">
        <template slot-scope="scope">
            <el-table :data="scope.row.quotations" :border="true" :stripe="true"
                      @selection-change="(p)=>handler(p,scope.row,dynaRef(scope.row))"
                      :ref="dynamicRef(scope.row)">
                <el-table-column type="selection" width="50"></el-table-column>
            </el-table>
        </template>
    </el-table-column>
</el-table>
