* line 线条
* @description 此组件一般用于显示一根线条用于分隔内容块有横向和竖向两种模式且能设置0.5px线条,使用也很简单
* @tutorial https://www.uviewui.com/components/line.html
* @property {String} color 线条的颜色(默认#e4e7ed)
* @property {String} length 长度竖向时表现为高度横向时表现为长度可以为百分比带rpx单位的值等
* @property {String} direction 线条的方向row-横向col-竖向(默认row)
* @property {String} border-style 线条的类型solid-实线dashed-方形虚线dotted-圆点虚线(默认solid)
* @property {Boolean} hair-line 是否显示细线条(默认true)
* @property {String} margin 线条与上下左右元素的间距,字符串形式,如"30rpx"
* @example <u-line color="red"></u-line>
