Vue自定义表格组件（v1.0）

Vue自定义表格组件

考虑到最近在使用element框架开发管理后台，用到表格组件的次数比较多，简单做了一个数据展示型的表格组件。

表格列提供4种数据处理展示，文本（默认）、图片、匹配文本、匹配文本按钮,做一下解释。

字段	类型	必填	备注
prop	String	是	后台返回的列字段（所有数据处理必填）
showImage	Boolean	否	style字段自定义样式
options	Object[Object]	否	匹配文本，格式如{1:{title:'文案1',type:'primary'}}
onAction	Function	否	用于匹配按钮事件传参
permission	Boolean	否	用于提供匹配按钮权限
