     * 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>
