element plus rules不起作用

<FormDrawer ref="formDrawerRef" :title="drawerTitle" @submit="handleSubmit">
    <el-form :model="form" ref="formRef" :rules="rules" label-width="80px" :inline="false">
      <el-form-item label="公告标题" props="title">
        <el-input v-model="form.title" placeholder="公告标题"></el-input>
      </el-form-item>
      <el-form-item label="公告内容" props="content">
        <el-input v-model="form.content" placeholder="公告内容" type="textarea" :rows="5"></el-input>
      </el-form-item>
    </el-form>
</FormDrawer>
