| | | * CodeInput 栅格系统的列 |
| | | * @description 该组件一般用于Layout 布局 通过基础的 12 分栏,迅速简便地创建布局 |
| | | * @tutorial https://www.uviewui.com/components/Layout.html |
| | | * @property {String | Number} span 栅格占据的列数,总12等份 (默认 12 ) |
| | | * @property {String | Number} offset 分栏左边偏移,计算方式与span相同 (默认 0 ) |
| | | * @property {String} justify 水平排列方式,可选值为`start`(或`flex-start`)、`end`(或`flex-end`)、`center`、`around`(或`space-around`)、`between`(或`space-between`) (默认 'start' ) |
| | | * @property {String} align 垂直对齐方式,可选值为top、center、bottom、stretch (默认 'stretch' ) |
| | | * @property {String} textAlign 文字水平对齐方式 (默认 'left' ) |
| | | * @property {Object} customStyle 定义需要用到的外部样式 |
| | | * @event {Function} click col被点击,会阻止事件冒泡到row |
| | | * @example <u-col span="3" offset="3" > <view class="demo-layout bg-purple"></view> </u-col> |
