-  * 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>
