* SwipeActionItem 滑动单元格子组件
|
* @description 该组件一般用于左滑唤出操作菜单的场景，用的最多的是左滑删除操作
|
* @tutorial https://www.uviewui.com/components/swipeAction.html
|
* @property {Boolean} show 控制打开或者关闭（默认 false ）
|
* @property {String | Number} index 标识符，如果是v-for，可用index索引
|
* @property {Boolean} disabled 是否禁用（默认 false ）
|
* @property {Boolean} autoClose 是否自动关闭其他swipe按钮组（默认 true ）
|
* @property {Number} threshold 滑动距离阈值，只有大于此值，才被认为是要打开菜单（默认 30 ）
|
* @property {Array} options 右侧按钮内容
|
* @property {String | Number} duration 动画过渡时间，单位ms（默认 350 ）
|
* @event {Function(index)} open 组件打开时触发
|
* @event {Function(index)} close 组件关闭时触发
|
* @example <u-swipe-action><u-swipe-action-item :options="options1" ></u-swipe-action-item></u-swipe-action>
