label-position=“left” 控制文字位置 但是先要控制文字宽度
label-width=“80px”

   <el-form :model="navigation" :rules="rules" ref="navigation" label-position="left"   label-width="80px">
             <el-form-item label="标题" prop="name">
               <el-input v-model="navigation.name"  :disabled="dialogState"></el-input>
             </el-form-item>
            <el-form-item label="链接" prop="jumpUrl">
               <el-input v-model="navigation.jumpUrl" :disabled="dialogState"></el-input>
             </el-form-item>
    </el-form>
