为了使用SpreadJS文件格式功能，您需要将相关的js文件链接添加到文档的head部分中，放在Spread链接下面。例如：
SpreadJS支持打开和保存sjs文件格式。它还支持导入和导出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
