需求：
选择会计科目的时候，会查出来对应的动态表格项，在切换进行选择不同的会计科目时，动态对应展示对应的动态表格项，且该动态表格实现下拉框选择不同的数据。
eg1：选择第一行会计科目，接口查出来有两个动态表格项
eg2：选择第二行会计科目，接口查出来有三个动态表格项
html代码：
<template> <div class="boxShadow"> <div style="margin-top: 20px"> <el-table
:data="dynamicTable" ref="multipleTable" style="width: 100%" border
tooltip-effect="dark"> <template v-for='(col) in dynamicTableCol'>
<el-table-column :label="col.chrName1" :prop="col.chrCode1"
:key="col.chrCode1"> <template slot-scope="scope"> <el-select
v-model="col.vModelData" @change="getNowSelData($event,col.chrName1)">
<el-option :label="item.chrName" :value="item.chrCode" v-for="(item, index) in
col.dynamicAllDatas" :key="index"></el-option> </el-select> </template>
</el-table-column> </template> </el-table> </div> </div> </template>
vue中的data：
js代码：
1、点击树形会计科目的时候 绑定@node-click="handleNodeClick3"方法(注释掉的可不看)
2、点击动态表格的时候绑定@change="getNowSelData($event,col.chrName1)"事件
3、focus会计科目的时候通过缓存展示之前不同会计科目所选的动态表格项
@focus=“selTableRow2(scope.$index)”
