|
* @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 ) |
