I have a tableau table with data as follows
Column1 Column2
abc 12
234
35
453
bcd 52
64
421
cde 222
def 83
94
now, I am looking for a third column, where I can get the count of the values within column 2 group by column 1.
so basically my desired solution is :
Column1 Column2 Column3
abc 12 4
234
35
453
bcd 52 3
64
421
cde 222 1
def 83 2
94
I am quite new to tableau, I would appreciate any assistance or advice. Thanks
