[英]How to count pairings of cells in spreadsheet
Let's say I have a spreadsheet that has two columns of data. 假设我有一个包含两列数据的电子表格。 For example:
例如:
A B
1 2
2 3
1 1
1 2
1 3
2 3
2 1
How could I count the total number of times each pair appears in the spreadsheet. 我如何计算每对在电子表格中显示的总次数。 In the example above, 1-2 should have a count of 3 (1 for 2-1, 2 for 1-2), 2-3 should have a count of 2etc
在上面的例子中,1-2应该有3个(1个为2-1,2个为1-2),2-3个应该有2个计数
Note that for Excel versions >2007 , you can use the new formula COUNTIFS
: 请注意,对于Excel版本> 2007 ,您可以使用新公式
COUNTIFS
:
[EDIT] Added the correct solution (credits to Chris Nielsen - see the comments) [编辑]添加了正确的解决方案(信用克里斯尼尔森 - 见评论)
=COUNTIFS($A$1:$A$12,A1,$B$1:$B$12,B1) + COUNTIFS($A$1:$A$12,B1,$B$1:$B$12,A1)
One way would be to use a SUMPROUDUCT in column C. That would give you a count of the number of times the combination in that row is encountered. 一种方法是在C列中使用SUMPROUDUCT。这将为您计算遇到该行中组合的次数。
=SUMPRODUCT(--($A$1:$A$7=A1),--($B$1:$B$7=B1))+SUMPRODUCT(--($A$1:$A$7=B1),--($B$1:$B$7=A1))
Following your example this would output: 按照你的例子,这将输出:
A B C
1 2 3
2 3 2
1 1 1
1 2 3
1 3 1
2 3 2
2 1 3
SUMPRODUCT can be tricky, you can read some good howtos here: SUMPRODUCT可能很棘手,你可以在这里阅读一些好的方法:
