卡顿的代码：
<!– <el-input
v-else
v-model="table.data[$index].watermeterCode"
:disabled="handleType === 'detail' || !row.isEdit"
></el-input> –>修改
解决的办法：
handleInput(index, field, value) {
this.$set(this.table.data[index], field, value)
// console.log(this.table.data[index])
},
<el-table-column
label="水表编号"
prop="watermeterCode"
show-overflow-tooltip
width="90"
>
<template v-slot:header>
<span class="warn">*</span>
<span>水表编号</span>
</template>
<template v-slot="{ row , $index}">
<span v-if="handleType === 'detail' || !row.isEdit">{{ row.watermeterCode }}</span>
<el-input
:key="row.id"
:ref="'nextNumInput-' + row.$index"
:controls="false"
:precision="0"
placeholder="请输入"
v-model="row.watermeterCode"
@blur="(event) => handleInput($index, 'watermeterCode', event.target.value)"
>
</el-input>
</template>
</el-table-column>
