格式如下:

1

3
4
5
6
7
8
9
10
11
12
13
14
{
    table: [
        {
            column1: 1,
            column2: 2,
            column3: 3
        },
        {
            column1: 1,
            column2: 2,
            column3: 3
        }
    ]
}

 

例如:

1
[{Code:MetaDataId,Name:MetaDataId},{Code:MetadataCode,Name:编号},{Code:SolutionName,Name:名称}]

格式化后:

1

[
    {
        Code: MetaDataId,
        Name: MetaDataId
    },
    {
        Code: MetadataCode,
        Name: 编号
    },
    {
        Code: SolutionName,
        Name: 名称
    }
]
