工作表公式引用集算表

概述本 Demo 展示了如何在普通工作表中使用公式引用集算表（TableSheet）的数据。Demo 创建了一个产品集算表（TableSheet1），然后在普通工作表中通过结构化引用和 QUERY 函数两种方式访问集算表数据，实现了产品统计、分类汇总、缺货筛选等多种数据分析功能。实现思路初始化 DataManager，添加产品表和类别表，并建立表关系创建集算表 TableSheet1，绑定产品数据视图在普通工作表中使用结构化引用（如 TableSheet1[Category]）引用集算表数据使用 COUNTA、SUM、UNIQUE、COUNTIF、MAXIFS、FILTER 等函数进行数据统计和分析使用 QUERY 函数从 DataManager 表中按条件查询数据代码解析初始化 DataManager 和表关系这段代码创建了两个数据表并建立了关系。addRelationship 方法将产品表的 CategoryId 字段与类别表的 Id 字段关联，使得产品视图可以访问类别信息。创建集算表并绑定视图视图定义了集算表的列结构，其中 Total Amount 和 Total Price 是计算列。[@UnitsInStock] 表示引用当前行的库存数量。使用结构化引用引用集算表结构化引用的格式为 TableSheetName[ColumnName]，与 Excel 表格引用方式一致。A5# 表示引用动态数组的溢出区域。使用 FILTER 函数筛选数据 FILTER 函数根据条件筛选集算表数据，返回动态数组结果。使用 QUERY 函数查询 DataManager 表 QUERY 函数直接从 DataManager 表中查询数据。格式为 QUERY("tableName?filter", columns)，其中 ?CategoryName="&B14 表示按类别名称筛选，A16:C16 指定返回的列。运行效果集算表 TableSheet1 显示产品数据，包含库存、订单数量和计算的总金额、总价格普通工作表显示多个数据汇总区域：产品总数和总价的统计按类别汇总的产品数量、订单成本、最高单价等信息缺货产品的筛选列表点击类别下拉框选择类别后，QUERY 函数自动查询并显示该类别的产品信息所有数据随集算表数据变化自动更新 API 参考 addRelationship 方法 sourceTable：源表对象 sourceFieldName：源表关联字段名 sourceRelationshipName：源表中关系名称 targetTable：目标表对象 targetFieldName：目标表关联字段名 targetRelationshipName：目标表中关系名称 QUERY 函数 tableAndRows：表名和筛选条件，格式为 "tableName?field=value" columns：可选，指定返回的列名或单元格区域常用查询格式：查询整个表：QUERY("table1") 按行索引查询：QUERY("table1#1") 按主键查询：QUERY("customer/abc@gmail.com") 按条件筛选：QUERY("order?status=success")
