一、点击保存对整个table校验
<template>
<div>
<el-button type="success" @click="handleAdd()">添加一条数据</el-button>
<el-form :model="ruleForm" ref="ruleForm">
<el-table :data="ruleForm.tableData" style="width: 100%">
<el-table-column
v-for="(item, index) in ruleForm.tableHeader"
:prop="item.keys"
:label="item.label"
:key="index"
>
<template slot-scope="scope">
<span v-if="scope.row.isSet">
<el-form-item
:prop="'tableData.' + scope.$index + '.' + item.keys"
:rules="{
required: true,
message: '值不能为空',
trigger: 'blur',
}"
>
<el-input v-model="scope.row[item.keys]"></el-input>
</el-form-item>
</span>
<span v-else>
{{ scope.row[item.keys] }}
</span>
</template>
</el-table-column>
<el-table-column label="操作">
<template slot-scope="scope">
<el-button
v-if="scope.row.isSet"
type="success"
@click="handleSave('ruleForm', scope.$index, scope.row)"
>
保存
</el-button>
<el-button
v-else
type="primary"
@click="handleEdit(scope.$index, scope.row)"
>
编辑
</el-button>
<el-button
type="danger"
@click="handleDelete(scope.$index, scope.row)"
>
删除
</el-button>
</template>
</el-table-column>
</el-table>
</el-form>
</div>
</template>
<script>
export default {
data() {
return {
ruleForm: {
tableHeader: [
{

},
],
tableData: [

},
methods: {
handleAdd() {
let row = {};
this.ruleForm.tableHeader.forEach((item, index) => {
row.isSet = true;
});
this.ruleForm.tableData.push(row);
},
handleEdit(index, row) {
row.isSet = true;
this.$set(this.ruleForm.tableData, index, row);
},
handleSave(ruleForm, index, row) {
this.$refs[ruleForm].validate((valid) => {
if (valid) {
row.isSet = false;
this.$set(this.ruleForm.tableData, index, row);
} else {
return false;
}
});
},
handleDelete(index, row) {
this.ruleForm.tableData.splice(index, 1);
},
},
};
</script>

</style>
二、点击确定对每一行el-table校验
<template>
<div class="formData">
<el-table :data="list" style="width: 100%">
<el-table-column prop="key" label="键" min-width="180">
<template slot-scope="{ row }">
<div v-if="!row.isModified">
{{ row.key }}
</div>
<el-form
v-else
:ref="'keyForm' + row.id"
label-width="0px"
:class="row.isKeyValid || row.isValueValid ? 'demo-ruleForm' : ''"
:model="row"
>
<el-form-item
prop="key"
:rules="[
{
validator: validateKey,
trigger: ['blur', 'change'],
id: row.id,
},
]"
>
<el-input v-model="row.key" placeholder="请输入内容"></el-input>
</el-form-item>
</el-form>
</template>
</el-table-column>
<el-table-column prop="value" label="值" min-width="180">
<template slot-scope="{ row }">
<div v-if="!row.isModified">

</div>
<el-form

:class="row.isKeyValid || row.isValueValid ? 'demo-ruleForm' : ''"
v-else
:model="row"
>
<el-form-item
prop="value"
:rules="[
