写一段二次封装element UI的表单

很高兴回答您的问题。以下是一段二次封装element UI的表单代码示例：

<template>
  <el-form ref="form" :model="formData" :rules="formRules" label-width="100px">
    <el-form-item label="姓名" prop="name">
      <el-input v-model="formData.name"></el-input>
    </el-form-item>
    <el-form-item label="年龄" prop="age">
      <el-input v-model.number="formData.age"></el-input>
    </el-form-item>
    <el-form-item label="性别" prop="gender">
      <el-radio-group v-model="formData.gender">
        <el-radio label="male">男</el-radio>
        <el-radio label="female">女</el-radio>
      </el-radio-group>
    </el-form-item>
    <el-form-item>
      <el-button type="primary" @click="submitForm">提交</el-button>
      <el-button @click="resetForm">重置</el-button>
    </el-form-item>
  </el-form>
</template>

<script>
export default {
  data() {
    return {
      formData: {
        name: '',
        age: '',
        gender: ''
      },
      formRules: {
        name: [
          { required: true, message: '请输入姓名', trigger: 'blur' }
        ],
        age: [
          { required: true, message: '请输入年龄', trigger: 'blur' },
          { type: 'number', message: '年龄必须为数字值' }
        ],
        gender: [
          { required: true, message: '请选择性别', trigger: 'change' }
        ]
      }
    }
  },
  methods: {
    submitForm() {
      this.$refs.form.validate(valid => {
        if (valid) {
          // 表单验证通过，提交表单数据
          console.log(this.formData)
        } else {
          // 表单验证失败，提示错误信息
          console.log('表单验证失败')
        }
      })
    },
    resetForm() {
      this.$refs.form.resetFields()
    }
  }
}
</script>
