为了使用 "SpreadJS文件格式 "功能，你需要将相关的js文件链接添加到文档的头部部分，在Spread链接的下面。比如说：
SpreadJS支持打开和保存sjs文件格式，也支持导入和导出xlsx、ssjson和csv文件格式。
例如:
class GC.Spread.Sheets.Workbook
GC.Spread.Sheets.SaveOptions
GC.Spread.Sheets.OpenOptions
GC.Spread.Sheets.ImportOptions
GC.Spread.Sheets.ExportOptions
GC.Spread.Sheets.ImportXlsxOptions
GC.Spread.Sheets.ExportXlsxOptions
GC.Spread.Sheets.ImportCsvOptions
.Spread.Sheets.ExportCsvOptions
GC.Spread.Sheets.ImportSSJsonOptions
GC.Spread.Sheets.ExportSSJsonOptions
