table组件 和 分页组件来自iview，在这里我根据公司业务再次做了一次封装，使用slot进行内容分发，可以随意放置input输入框和button按钮 ，再使用props向子组件传递参数，使用emit属性向父组件传递事件，

代码如下
《子组件》
<template>
<div style="">
<div class="search-bar run-search-bar" style="background:none;">
<div>
<!-- align="right" style="margin:5px" -->
<slot name="handle-bar"></slot>
</div>
<div>
<slot name="search-bar"></slot>
</div>
</div>
<div class="single-table-con">
<div class="table-bar">
<slot name="table-bar"></slot>
</div>
<Table size="small" ref="table" :loading="loading" @on-current-change="onCurrentChange" :highlight-row="highlightRow" :data="tableData" :columns="tableColumns" @on-selection-change="selectionChange" @on-sort-change="sortHandle" @on-row-click="rowClickHandle" stripe></Table>
<div style="margin: 10px;overflow: hidden" v-if="isPage">
<div style="float: right;">
<Page :placement="placement" :total="total" :show-total="showTotal" :page-size-opts="pageSizeOpts" :show-sizer="showSizer" :page-size="param.page.pageSize" :current="param.page.currentPage" @on-change="changePage" size="small" @on-page-size-change="changePageSize"></Page>
