| 	 * grid 宫格布局 | ||||
| 	 * @description 宫格组件一般用于同时展示多个同类项目的场景,可以给宫格的项目设置徽标组件(badge),或者图标等,也可以扩展为左右滑动的轮播形式。 | ||||
| 	 * @tutorial https://www.uviewui.com/components/grid.html | ||||
| 	 * @property {String | Number}	col			宫格的列数(默认 3 ) | ||||
| 	 * @property {Boolean}			border		是否显示宫格的边框(默认 false ) | ||||
| 	 * @property {String}			align		宫格对齐方式,表现为数量少的时候,靠左,居中,还是靠右 (默认 'left' ) | ||||
| 	 * @property {Object}			customStyle	定义需要用到的外部样式 | ||||
| 	 * @event {Function} click 点击宫格触发 | ||||
| 	 * @example <u-grid :col="3" @click="click"></u-grid> | ||||
