1、页面的样式：

<el-row>
        <el-col :span="10">
          <el-table
            :data="data1"
            border
            ref="selection"
            @selection-change="checkAll"
            style="width: 100%">
            <el-table-column
              type="selection"
              width="30">
            </el-table-column>
            <el-table-column
              prop="date"
              label="日期"
              width="100"
            >
            </el-table-column>
            <el-table-column
              prop="name"

              width="100"
            >
            </el-table-column>
            <el-table-column
              prop="address"
              label="地址"
            >
            </el-table-column>
          </el-table>
        </el-col>
        <el-col :span="4">
          <div class="opSetting">
            <div @click="handelSelect">
              <el-button icon="el-icon-d-arrow-right" :disabled="nowSelectData.length?false:true" :size="buttonSize" type="primary" >
                选中
              </el-button>
            </div>
            <div class="spacing" @click="handleRemoveSelect">
              <el-button icon="el-icon-d-arrow-left" :disabled="nowSelectRightData.length?false:true" :size="buttonSize" type="primary">
                取消
              </el-button>
            </div>
          </div>
        </el-col>

        <el-col :span="10">
          <el-table
            :data="selectArr"
            border
            ref="selection"
            @selection-change="checkRightAll"
            style="width: 100%">
            <el-table-column
              type="selection"
              width="30">
            </el-table-column>
            <el-table-column
              prop="date"
              label="日期"
              width="100"
            >
            </el-table-column>
            <el-table-column
              prop="name"

            >
            </el-table-column>
            <el-table-column
              prop="address"
              label="地址"
            >
            </el-table-column>

          </el-table>
        </el-col>

      </el-row>

2、js代码

<script>

      options: [],
      value: '',
