? 1   ? 1  

格式如下：

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 monospace !important; font-size: 1em !important; font-style: normal !important; font-weight: normal !important; vertical-align: baseline !important; float: none !important; position: static !important; min-height: inherit !important; box-sizing: content-box !important;">{     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 2 3 4 5 6 7 8 9 10 11 12 13 14 [     {         Code: MetaDataId,         Name: MetaDataId     },     {         Code: MetadataCode,         Name: 编号     },     {         Code: SolutionName,         Name: 名称     } ]
