FILTER函数基于布尔数组来过滤数组。
参数
必需
描述
array
是
要进行过滤的数组或区域
include
是
一个布尔数组，其高度或宽度与要进行过滤的数组相同
[if_empty]
否
如果所包含数组中的所有值均为空（filter结果为空）的返回值
注意：
FILTER 函数仅在allowDynamicArray为true时有效。
FILTER 函数将返回一个数组，如果该数组是公式的最终结果，则将溢出。
如果您的数据集有可能返回空值，请使用第3个参数（[if_empty]）。 否则，将导致“ #CALC！”错误。
如果include参数的任何值是错误（＃N/A，＃VALUE等）或无法转换为布尔值，则FILTER函数将返回错误。
