VUE 表格中添加表单验证

            表格数据有多行，针对每一行的input输入值加入表单验证，关键代码是：:prop="'data1.'+scope.$index+'.newBudget'"  

<div>
        <el-form ref="form1" :model="readyUpdateNodes" label-width="150px">
          <el-table
            :data="readyUpdateNodes.data1"
            :span-method="changeUpdateType"
            align="center"
            border
            stripe
            class="table1"
          >
            <el-table-column prop="campaignName" align="center" label="广告组名称">
              <template slot-scope="{row}">
                {{ row.campaignName }}
              </template>
            </el-table-column>
            <el-table-column prop="budget" align="center" label="当前预算">
              <template slot-scope="{row}">
                {{ (row.budgetModeDesc ? row.budgetModeDesc : '') + '\t' + (row.budget ? row.budget : '--') }}
              </template>
            </el-table-column>
            <el-table-column align="center" label="修改预算">
              <template slot-scope="scope">

                <el-form-item label="预算" :prop="'data1.'+scope.$index+'.newBudget'" :rules="readyUpdateNodes.fromaDataRules.newBudget">
                  <el-input v-model.number="scope.row.newBudget" @input="updateBudget($event)" />
                  <span v-if="scope.row.newBudget==='0'||scope.row.newBudget===0" class="messageTip">0为不限预算</span>
                </el-form-item>

              </template>
            </el-table-column>
          </el-table>
        </el-form>
      </div>

data() {
var validateBuget = (rule, value, callback) => {
      if (value === '') {
        callback(new Error('请输入预算'))
      }
      //   if (value === 0 || value === '0') {
      //     callback(new Error('0为预算不限'))
      //   }
      if ((value > 0 && value < 300) || value > 20000) {
        callback(new Error('预算金额范围为[300, 20000]，请修改'))
      }
      callback()
    }
return {
readyUpdateNodes: {
        'data1': [],
        'fromaDataRules': {
          newBudget: [
            { required: true, message: '请输入预算', trigger: 'blur' },
            { validator: validateBuget, trigger: 'blur' }
          ]
        }
      }
}
}
