优秀的select和随机化
我仍然试图弄清楚这一点。 我在excel的一张表中有这个数据。
City Risk Level Facility 1 Extremely Low Risk Facility 2 Very High Risk Facility 3 Very Low Risk Facility 4 Low Risk Facility 5 Moderate Risk Facility 6 Moderate Risk Facility 7 High Risk Facility 8 Extremely Low Risk Facility 9 Very Low Risk Facility 10 Low Risk Facility 11 Moderate Risk Facility 12 Extremely Low Risk Facility 13 Very High Risk Facility 14 Very Low Risk Facility 15 Low Risk Facility 16 Moderate Risk Facility 17 Highly Moderate Risk Facility 18 High Risk Facility 19 Extremely Low Risk Facility 20 Very Low Risk Facility 21 Low Risk Facility 22 Moderate Risk Facility 23 Highly Moderate Risk Facility 24 High Risk Facility 25 Very High Risk Facility 26 Extremely Low Risk Facility 27 Very Low Risk Facility 28 Low Risk Facility 29 Moderate Risk Risk Levels Desired Extremely Low Risk 3 Very Low Risk 4 Low Risk 4 Moderate Risk 5 Highly Moderate Risk 2 High Risk 2 Very High Risk 1 我想知道是否有一个公式可以从每个风险等级中select所需的设施数量。 例如：3个“非常低风险”的设施，那么有4个“非常低风险”的设施，4个“低风险”设施，5个“中等风险”的设施……等等随机，我希望设施的名称显示在列中，而不是行。
请让我知道我能做到这一点。
非常感谢你提前。
你可以使用这个公式：
=IF(COLUMN(A:A)<=$E2,INDEX($A:$A,AGGREGATE(15,6,ROW($B$2:$B$30)/(($B$2:$B$30=$D2)*(COUNTIF($E$2:E2,$A$2:$A$30)=0)),RANDBETWEEN(1,COUNTIF($B$2:$B$30,$D2)-COLUMN(A:A)+1))),"")
