需求：

1. 根据当前登录用户角色动态控制是否展示业务经理查看状态列和大区经理查看状态列
2. 列表中为金额的列，其值如果全为0则该列不展示

实现：

<!-- 此处的Tablepage为重新封装过后的表格组件 -->
<template>
	<div>
		<Tablepage ref="table" :data="listData" :total="total" :columns="newColumns" :pagination="true" border @change-page="onChangePage" @reset="onReset" @on-current-change="onCurrentChange" @on-selection-change="onSelectionChange" show-btn :init-data="false">
			<template slot="searchform">
				<!-- ......此处省略查询条件 -->
			</template>
		</Tablepage>
	</div>
</template>
