Excel - 如果特定单元格与上面的单元格不同，如何突出显示整行？

Question

I am trying to apply conditional formatting in excel in which each first occurrence in a column has a highlight on the entire row. The desired result is as follows:

A	B
2
2
8	Highlight this entire row
5	Highlight this entire row
5
7	Highlight this entire row

I currently have the formula "A3<>A2", but that highlight the last occurrence instead of the first. I don't know how to apply the highlight to all cells on the same row.

UPDATE: Apparently excel behaves differently for text and numeric values. My data looks like this:

A	B
Apple
Apple
Banana	Highlight this entire row
Kiwi	Highlight this entire row
Kiwi
Apple	Highlight this entire row

Answer 1

Conditional Formatting - Entire Row For First Occurrence in Column

• The issue you are facing is that you have selected eg the range 2:10 (focus on 2 ) and eg you are applying the corrected ( $ ) formula =$A3<>$A2 which does what is expected: it highlights the last occurrence in a group ie if the value of the next row ( 3 ) is different than the value of the current row ( 2 ) then highlight row 2 .
• To highlight the first occurrence in a group, you need =$A2<>$A1 as correctly posted by user11222393 since the first row you selected is row 2 ie if the value of the previous row ( 1 ) is different than the value of the current row ( 2 ) then highlight row 2 .
• My solution will work similarly if the data is sorted. It will not highlight the first row of repeating groups though, as illustrated in the screenshot below.
• You will notice the difference between the solutions best by sorting the data in another column. Mine should have fewer highlighted rows.

Usage

• Select the entire rows of the range and goto Home -> Conditional Formatting -> New Rule -> Use formula... (you know the drill) and eg use

  =COUNTIF($A$2:$A2,$A2)=1

  for the first row being row 2.

Answer 2

=$A2<>$A1

Take a look at $ symbols. If you don't use it it will highlight only 1 cell, because it will compare A2 to A1 , B2 to B1 and so on.

Result:
