格式如下:
{ "table": [ { "column1": 1, "column2": 2, "column3": 3 }, { "column1": 1, "column2": 2, "column3": 3 } ] }
例如:
[{"Code":"MetaDataId","Name":"MetaDataId"},{"Code":"MetadataCode","Name":"编号"},{"Code":"SolutionName","Name":"名称"}]
格式化后:
[ { "Code": "MetaDataId", "Name": "MetaDataId" }, { "Code": "MetadataCode", "Name": "编号" }, { "Code": "SolutionName", "Name": "名称" } ]
