SUMIF 函数可用于计算子表单中满足某一条件的数字相加并返回和。
2. 函数用法
SUMIF(range, criteria, [sum_range])

SUMIF 函数可用于计算子表单中满足某一条件的数字相加并返回和。
2. 函数用法
SUMIF(range, criteria, [sum_range])
其中各参数的含义及使用方法如下 range必需根据 criteria 的条件规则进行检测的判断字段。支持的字段包括子表单中的数字、单行文本、下拉框、单选按钮组 criteria必需用于判断的条件规则。支持的形式和使用规则如下表
支持形式是否需要加引号示例注意事项数字不需要20、32表达式需要“32”、!苹果支持的运算符号包括、、、!、、文本需要“苹果”、水果字段不需要字段1在主表字段中使用 SUMIF 函数时只能选择主表字段2在子表字段中使用 SUMIF 函数时只能选择择主表字段和当前子表字段
3. 函数示例
如计算入库明细中产品类型为「水果」的全部入库数量则可以在「水果类数量总计」字段设置公式为 4. 代码实战
首先我们在function包下创建math包在math包下创建SumIfFunction类代码如下
