<template slot="unitShow" slot-scope="text, record">

slot="unitShow" 表示插槽名（见具名插槽）

slot-scope="text, record" 表示作用域插槽接收从<a-table>组件传递进来的两个参数，其中：

text是<a-table>组件定义的 当前插槽slot="unitShow"对应的数据项'unit'的文本值

{title: '单位',dataIndex: 'unit',scopedSlots: {customRender: 'unitShow'}
},

 record是<a-table>组件定义的 当前行的全部数据

通过输出{{ text }}和{{ record }}可以看出：

              <h4>text内容{{ text }}</h4>

              <h4>record内容{{ record }}</h4>
