用户可以在表单中，像引用表格一样使用结构引用来引用集算表。
集算表名称是表的名称，列标题是表的列。下面是示例。
它也支持A1/R1C1参考样式，但它不容易阅读。A1/R1C1参考样式可以在单元格公式、图表和条件格式中使用。
用户可以使用QUERY函数从DataManager表中获取数据。
QUERY语法
返回类型
示例
整个表
QUERY("table1")
这个列
QUERY("table1", "column1")
单一数据
QUERY("table1#1", "column1")QUERY("customer/abc@gmail.com", "name)
整个行
QUERY("table1#1")QUERY("customer/abc@gmail.com")
筛选行
用户可以使用简单的行筛选器。
类型
示例
按照行索引
QUERY("table1#1")
按照行主键
QUERY("customer/abc@gmail.com")
按照键值对筛选
QUERY("order?status=sucess")
多列
用户可以通过使用数组来选择许多列。
类型
示例
按列引用
QUERY("order?status=shipping", {"order date", "address", "Cargo weight"})
通过维度引用
QUERY("order?status=shipping", A1:D1)
