vue组件的创建和使用

1.src文件夹下的components-》table -》index.js

import MTable from './table.vue';

import MyTable from './table1.vue';

export default (Vue)=>{

Vue.component("MTable", MTable);

Vue.component("myTable", MyTable)

}

2.src文件夹下的components-》table -》table1.vue

/**

* 自定义table组件

********** columns：表头信息 **********

* @type: index -- 序号

* checkbox -- 多选框

* date -- 日期组件

* imgUpdata -- 图片上传

* select -- 下拉框

* button -- 按钮

* @width：宽

* @title：表头

* @thClass：表头class

* @tdClass：表列class

* @key：字段名

* @onBlur：失焦事件

* @onChange： change事件

* @onClick： click事件

* @tdClass：表列class

* @option：｛

optionList：下拉框的列表

optionValueKey: 绑定的value值得字段名,

optionLabelKey: []，数组最多2个label字段名

* ｝

* @filterable：下拉框可搜索

* @disabled：下拉框禁用

* @clearable：可清空下拉框内容

* @butTitle： button名

*CheckboxGroup 是一个多选框组件

* 注：optionList必须获取到list再赋值

***************** tableData：列表数据 **********

******* tableCheck：多选框绑定行的index ********

***********************************************

* 具体参考addAdvanceOrde.vue文件 *
