用el-table 添加 移除 方式处理 穿梭框 从左与右的双向选择

1. 通过条件 筛选 效果图如下
   

2. 主业务逻辑层代码

<div>
	<el-input v-model="teachName" placeholder="输入姓名搜索" style="width:200px;" size="mini" clearable />
	<el-button type="primary" size="mini" icon="el-icon-search" style="margin-left: 10px;" @click="getData">查询</el-button>
  </div>
  <el-col :span="12">
	<el-table :data="tabDataLeft" border style="100%" size="mini" fit highlight-current-row>
	  <el-table-column label="可选">
		<!-- <el-table-column label="序号" type="index" :index="courseIndex" /> -->
		<el-table-column prop="fullName" label="姓名"></el-table-column>
		<el-table-column prop="workPlace" label="单位"></el-table-column>
		<el-table-column prop="position" label="职务"></el-table-column>
		<el-table-column label="添加" width="50">
		  <template slot-scope="scope">
			<el-button type="text" icon="el-icon-circle-plus-outline" class="underline btn24" size="mini" @click="handleAddData(scope.$index)"></el-button>
		  </template>
		</el-table-column>
	  </el-table-column>
	</el-table>
	<!-- <pagination v-show="total>0" :total="total" :page.sync="page" :limit.sync="limit" @pagination="getData" /> -->
  </el-col>
 <el-col :span="12">
	<el-table :data="tabDataRight" border style="100%" size="mini" fit highlight-current-row>
	  <el-table-column label="已选">
		<el-table-column prop="fullName" label="姓名"></el-table-column>
		<el-table-column prop="workPlace" label="单位"></el-table-column>
		<el-table-column prop="position" label="职务"></el-table-column>
		<el-table-column label="移除">
		  <template slot-scope="scope">
			<el-button type="text" icon="el-icon-remove-outline" class="underline btn24" size="mini" @click="handleRemoveData(scope.$index)">移除</el-button>
		  </template>
		</el-table-column>
	  </el-table-column>
	</el-table>
  </el-col>

3. 调用方法

handleAddData(index) {
    
            // 添加
  this.tabDataRight.push(this.tabDataLeft[index])        //右边添加
  this.tabDataLeft.splice(index, 1)                      //左边移除
},
handleRemoveData(index){
    
            // 移除
  this.tabDataRight.splice(index, 1)
},
getData(){
    
             // 获取信息列表
  var teachDto = ....     // 构建查询dto this.page 分页对象
  resTeachersList(teachDto, this.page).then((res) => {
    
                
    this.tabDataLeft = res.data.records
    this.total = res.data.total
  })
},
