2. Realize the merged column display of [Total]

You need to change the source code of iview's Table component here.

• The data format is as follows, control rows, control columns, control the number of merges, and control the display data

[
    {// 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
            }
        ]
    }
]

• The following It is a modified source code. It does not currently support events such as mouse movement into the table.

     table-body.vue:33
