* @tutorial https://uviewpro.cn/zh/components/line.html
|
||
* @property {String} color 线条的颜色(默认var(--u-border-color))
|
||
* @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>
