-  * 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true)
 
-  * @property {Boolean} hover-class 点击宫格的时候,是否显示按下的灰色背景(默认false)
 
-  * @event {Function} click 点击宫格触发
 
-  * @example <u-grid :col="3" @click="click"></u-grid>
