之前做得比较多的校验是在el-form表单里做的，但有时也遇到，需要在table内输入数据，然后校验输入的数据是否符合要求的情况。因此记录一下。

思路：
1.需要借助el-form的校验，el-table外层嵌套一层el-form，使用el-form的校验机制
2.由于每行都需要校验，因此需要借助scope.$index
3.借助一个提交按钮，测试校验

效果：
1.不输入数据，直接点击“提交”触发校验，由于数据没有输入，校验不通过，给出校验提示
2.点击输入框输入，点击某一个字段，即正在输入状态，这个字段的校验结果就会被清除（clearValidate）
3.数据都填好之后，点击“提交”，再次触发校验
4.校验通过，显示全屏提示是否提交，点击“确定”即可，控制台会打印“校验通过

    <div id="app"><el-form class="base-form" ref="baseForm" :model="baseForm" :rules="rules" auto-complete="on"><el-table ref="table-input" class="table" highlight-current-row :data="baseForm.demoList"><el-table-column label="姓名" show-overflow-tooltip><template slot-scope="scope"><el-form-item :prop="'demoList.'+scope.$index+'.name'" :rules="rules.name" class="all"><el-input v-model="scope.row.name" placeholder="请输入" clearable @focus="$refs.baseForm.clearValidate(`demoList.${scope.$index}.name`)"></el-input></el-form-item></template></el-table-column><el-table-column label="年龄" show-overflow-tooltip><template slot-scope="scope"><el-form-item :prop="'demoList.'+scope.$index+'.age'" :rules="rules.age" class="all"><el-input v-model="scope.row.age" placeholder="请输入" clearable @focus="$refs.baseForm.clearValidate(`demoList.${scope.$index}.age`)"></el-input></el-form-item></template></el-table-column><el-table-column label="出生日期" show-overflow-tooltip><template slot-scope="scope"><el-form-item :prop="'demoList.'+scope.$index+'.birthday'" :rules="rules.birthday" class="all"><el-date-picker placeholder="请选择" v-model="scope.row.birthday" format="yyyy-MM-dd" clearable @focus="$refs.baseForm.clearValidate(`demoList.${scope.$index}.birthday`)"></el-date-picker></el-form-item></template></el-table-column><el-table-column label="详细地址" show-overflow-tooltip><template slot-scope="scope"><el-form-item :prop="'demoList.'+scope.$index+'.address'" :rules="rules.address" class="all"><el-input v-model="scope.row.address" placeholder="请输入" clearable @focus="$refs.baseForm.clearValidate(`demoList.${scope.$index}.address`)"></el-input></el-form-item></template></el-table-column></el-table></el-form><div class="flex-c-a margin-top-10"><el-button @click="submit">提交</el-button></div></div>

data数据

           baseForm: {demoList: [{name: "",age: "",birthday: "",address: ""}]},index: 0,rules: {name: [{required: true,message: "请输入姓名",trigger: "blur"}],age: [{ required: true, message: "请输入年龄", trigger: "blur" }],birthday: [{ required: true, message: "请选择出生日期", trigger: "change" }],address: [{ required: true, message: "请输入详细地址", trigger: "blur" }],}

method：
给一个提交按钮，测试校验

// 提交核对账目
submit() {this.$refs.baseForm.validate((valid) => {if (valid) {this.$confirm("您确定【提交】？", "提示", {confirmButtonText: "确定",cancelButtonText: "取消",type: "warning"}).then(() => {console.log("校验通过")})}})
}

例子里使用的css：

  .all {width: 100%;}.flex-c-a {display: flex;align-items: center;justify-content: space-around;}.margin-top-10 {margin-top: 10px;}.base-form.el-form-item__content {margin-left: 0;}
