  	 * 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://uview-plus.jiangruyi.com/components/line.html
  	 * @property {String}			color		线条的颜色 ( 默认 '#d6d7d9' )
  	 * @property {String | Number}	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px单位的值等 ( 默认 '100%' )
  	 * @property {String}			direction	线条的方向,row-横向,col-竖向 (默认 'row' )
  	 * @property {Boolean}			hairline	是否显示细线条 (默认 true )
  	 * @property {String | Number}	margin		线条与上下左右元素的间距,字符串形式,如"30px"  (默认 0 )
  	 * @property {Boolean}			dashed		是否虚线,true-虚线,false-实线 (默认 false )
  	 * @property {Object}			customStyle	定义需要用到的外部样式
  	 * @example <u-line color="red"></u-line>
