1.表格

自定义错误信息显示div

            <el-form-item label="租赁价格" prop="supplierId"><el-table-column prop="salePrice" label="销售价" align="center"><template slot-scope="scope"><el-form-item label="" :prop="`leasingCycleInfo[${scope.$index}].salePrice`":rules="rules['salePrice']"><el-input v-model.trim="scope.row.salePrice" clearable placeholder="请输入销售价"></el-input><div v-if="errors[scope.$index] && errors[scope.$index].salePrice" class="error-message">{{errors[scope.$index].salePrice }}</div></el-form-item></template></el-table-column></el-table></el-form-item>

2.校验方法中，使用对象存储错误信息

data() {  
var validateSalePrice = (rule, value, callback) => {let curIdx = this.equipmentLeaseForm.leasingCycleInfo.findIndex(item => item.salePrice === value);console.log(curIdx);if (value === '') {if (curIdx != -1) {this.$set(this.errors, curIdx, { salePrice: "请输入销售价格" });}callback(new Error('请输入销售价格'));} else if (value < 0) {if (curIdx != -1) {this.$set(this.errors, curIdx, { salePrice: "销售价格不能小于0" });}callback(new Error('销售价格不能小于0'));} else {delete this.errors.salePrice;callback();}};return {
...rules: {salePrice: [{ validator: validateSalePrice, trigger: "blur" }]},errors: [],
}

3.定义错误信息样式

  .error-message {color: #F56C6C;font-size: 12px;line-height: 1;padding-top: 4px;}

4.处理方式二，使用el-tooltips进行提示
