样式问题 uni-form-item lable标签 宽一些样式怎么改

uni-forms 有个属性 :labelWidth="数字" 就ok了

			<u-form :model="form" ref="uForm">
				<u-form-item label="姓名" :labelWidth='140'>
					<u-input v-model="name" />
				</u-form-item>
				<u-form-item label="联系电话" :labelWidth='140'>
					<u-input v-model="name" />
				</u-form-item>
				<u-form-item label="上次登陆" :labelWidth='140'>
					<u-input v-model="name" />
				</u-form-item>
			</u-form>
