small, index, row, excel
=SMALL(IF($A$1:$A$7=$A$10,ROW($A$1:$A$7)),ROW(1:1))
=INDEX($A$1:$B$7,SMALL(IF($A$1:$A$7=$A$10,ROW($A$1:$A$7)),ROW(1:1)),2)
=IF(ISERROR(INDEX($A$1:$B$7,SMALL(IF($A$1:$A$7=$A$10,ROW($A$1:$A$7)),ROW(1:1)),2)),"",INDEX($A$1:$B$7,SMALL(IF($A$1:$A$7=$A$10,ROW($A$1:$A$7)),ROW(1:1)),2))
我想問以上3 equations, 應該點了解?
因為我唔明白eg, ROW($A$1:$A$7)),ROW(1:1)
謝謝
