iview的Table组件表头分组
合并表头
合并列，展示[合计]
表头有重复的key，数据如何匹配
实现合并列——需要修改Table组件来实现
根据iview提供的demo可以看出，表头的编辑是比较容易的，只需要根据格式编写即可。
问题：表头有重复的key，表头和表数据如何匹配
解决：
需要分组的表头 key_供货人ID
需要分组的表数据 key_供货人ID

]此处需要更改iview的Table组件的源码。
数据格式如下，控制行，控制列，控制合并个数，控制展示数据
[
{// 每一条，表示有一行
"total":"合计", // 展示的数据
"key":"total", // 表头的key
"align":"center",
"ellipsis":true,
"colspan":"2", // 需要计算合并列的个数
"tableBody":[ // tableBody.length 表示有多少个值
{
"total_11113173785":"523700.00",
"key":"total_11113173785",
"colspan":"2",
"align":"center",
"ellipsis":true
},
{
"total_11113173838":"991100.00",
"key":"total_11113173838",
"colspan":"2",
"align":"center",
"ellipsis":true
}
]
}
]以下是修改的源码，暂时不支持表格的鼠标移入等事件
table-body.vue:33
<!-- ++++++++++++++++ 2018年8月7日16:49:00 合并列单元格 start +++++++++++++++++++++ --> <template> <template> <table-tr> <td> <cell></cell> </td> <template> <td> <cell></cell> </td> </template> </table-tr> </template> </template> <!-- ++++++++++++++++ 合并列单元格 end +++++++++++++++++++++ -->
