element-ui使用el-select疑問

element-ui在使用el-select的時候, 用戶輸入XXX,然后去匹配用戶輸入的值. 如果只有一條數(shù)據(jù)的時候,可以直接選中嗎?不要再讓用戶選了. 網(wǎng)上找了很多資料也沒有實現(xiàn),有沒有知道怎么做的.
頁面如下圖

圖片部分對應的代碼大致如下

<el-table :data="tableData" highlight-current-row border ref="tableData">
        <el-table-column prop="serialNumber" label="序號" width="80">
          <template scope="scope">
            <span>{{scope.$index+1}}</span>
          </template>
        </el-table-column>
        <el-table-column label="商品編碼" width="100">
          <template scope="scope">
            <el-select v-model="scope.row.valuebz" filterable remote @change="selectRelation(scope.$index,scope.row, $event)" placeholder="請輸入關鍵詞" :remote-method="remoteMethod" :loading="loading">
              <el-option v-for="item in options4" :key="item.value" :label="item.label" :value="item.value">
              </el-option>
            </el-select>
          </template>
        </el-table-column>
        <el-table-column prop="barCode" label="條形碼"></el-table-column>
        <el-table-column prop="commodityName" label="商品名稱"></el-table-column>
        <el-table-column prop="commoditySpec" label="規(guī)格" width="100"></el-table-column>
        <el-table-column label="箱數(shù)" width="100">
          <template scope="scope">
            <el-input v-model="scope.row.boxQuantity" @keyup.native="handleBoxNumChange(scope.$index, scope.row,$event)" :maxlength="10"></el-input>
          </template>
        </el-table-column>
        <el-table-column prop="boxCapacity" label="箱規(guī)"></el-table-column>
        <el-table-column label="入庫數(shù)量" width="100">
          <template scope="scope">
            <el-input id="txt" v-model="scope.row.ratio" v-show="scope.row.isShow" @keyup.native="handleInNumChange(scope.$index, scope.row,$event)" :maxlength="10"></el-input>
          </template>
        </el-table-column>
        <el-table-column prop="commodityUnit" label="單位" width="60"></el-table-column>
        <el-table-column label="操作" width="120">
          <template scope="scope">
            <el-button type="danger" size="small" @click.stop="addOneRow(scope.$index, scope.row)">增加</el-button>
            <el-button size="small" type="danger" @click.stop="handleDelete(scope.$index, scope.row)">刪除</el-button>
          </template>
        </el-table-column>
      </el-table>

整個頁面邏輯比較多,所以原諒我不能把整個頁面代碼放上來.我有試著去修改v-model的值,但是這樣做如果有多行數(shù)據(jù),修改最后一行的數(shù)據(jù)會導致前面所有的行都跟著變,是把scope.row給傳進去了.
