保存和打印

TableSheet支持序列化为JSON,打印,导出到Excel,以及另存为PDF。

JSON序列化以及反序列化 TableSheet的JSON序列化以及反序列化是由Workbook的toJSON以及fromJSON方法驱动的。 建议在fromJSON之后使用setDataView。 导出Excel TableSheet导出Excel同样是由GC.Spread.Excel.IO的save方法驱动的。 建议在导出Excel的时候将includeBindingSource选项置为true。 在导出Excel时,可以将saveAsView设置为true。 导出PDF TableSheet导出PDF是由Workbook的savePDF方法驱动的。 对于打印或者导出PDF,用户可以通过使用printInfo方法自定义打印信息。 打印 TableSheet的打印是由Workbook的print方法驱动的。
