vue Table组件封装 - 渲染列表、不同表格列、分页、位于编辑面板中
效果描述：点击输入框弹出table面板，面板包括标题、列表分页、检索条件、确定取消安钮、单选全选框。面板回显已选中条目，切换页时仍能显示。思路：组件中包括面板整体样式、标题 、按钮、分页组件；页面中将搜索条件、th、tr用slot传入组件模板中，形成每页的table。监听面板打开关闭的变量进行重新渲染，点击确定时页面父组件监听事件传出选中条目的数组，符合条件则执行面板关闭及后续。点击检索按钮时通.

效果描述：点击输入框弹出table面板，面板包括标题、列表分页、检索条件、确定取消安钮、单选全选框。面板回显已选中条目，切换页时仍能显示。
思路：组件中包括面板整体样式、标题 、按钮、分页组件；页面中将搜索条件、th、tr用slot传入组件模板中，形成每页的table。监听面板打开关闭的变量进行重新渲染，点击确定时页面父组件监听事件传出选中条目的数组，符合条件则执行面板关闭及后续。点击检索按钮时通过this.$refs.comName.method(‘tag’);调用组件内检索方法、改变组件内检索条件。
技能点：主要为slot使用方法以及业务梳理，合理提取组件。外表及方法共用，仅传入url和检索条件，确定时传出选定数组。若为多个table且表头不同，则在一个父组件内通过变量控制显示与数组赋值。slot用v-if控制显示（不可v-show，此属性为控制dom元素display属性），不可出现同名slot，但slot内可用template显示不同的html内容。 slot-scope=" " 为vue2.5+中写法。
<table class="table table-hover table-bordered">

<slot name="ths"></slot>
<slot name="item"
v-for="item in items"
:item="item">

<th>ID</th>
<th>Project</th>
<th>Version</th>
</tr>
