vue中elmentui两个eltable问题

问题遇到的现象和发生背景

做了一个人员选择界面，用了两个el-table，第一个el-table自带的数组val(或者叫selection)，第二个已选人员名单数组mutipleSelection但是下图中的已选人员名单（第二个el-table）中的移除功能要怎么同步移除第一个el-table中的选择状态呢？就是第二个表格的删除功能无法访问到第一个eltable的val数组
2单选没有问题，但是全选后再点击一次会删除或添加两个内容

<template>
    <div class="pSelect">
        <div class="pHeader">
            <div class="pText">选择人员</div>
            <div class="pInput">

问题1，deleteRow参数搞反了，不过这不是主要问题，要用api来切换勾选取消勾选。要不全选状态栏不会更新。

问题2，不需要这2个，用selection-change，直接更新multipleSelection为传入的val（当前el-table的选中行），这样上面调用deleteRow也会触发这个事件自动更新multipleSelection
用下面的就正常了
