跨工作簿的引用包含用方括号内括起来的源工作簿名称，后跟工作表名称加上“!” 和单元格引用或范围引用。 例如：
=[Calc.xlsx]Sheet1!A1
=[Calc.xlsx]Sheet1!A1:B3
=[Detail]Sheet1!A1:B3 ("Detail" 是源工作簿文件的全名)
如果文件或工作表名称包含无效字符，则工作簿和工作表名称需要用单引号引起来。
='[Calc (0).xlsx]Sheet1'!A1
如果定义了源工作簿路径，SpreadJS 将在方括号前添加文件路径。 文件路径还可用于选择可能具有相同文件名的不同源文件。
='C:\Users\Administrator\Downloads[calc.xlsx]Sheet1'!$C$6
SpreadJS 提供了 getExternalReferences 和 updateExternalReference API 来获取和设置工作簿的外部数据源。
这是设置跨工作簿公式以及设置外部源的示例：
