column with an incremented serie

[lucy]

Hello

I would like to create a column in which a series incremented from 1 starts again with each new item of data in the Name column.

As in the example below

Name	Serie​
a	1​
a	2​
a	3​
b	1​
b	2​
b	3​
b	4​
c	1​
c	2​
d	1​
e	1​
e	2​
e	3​
e	4​
e	5​
e	6​
e	7​
f	1​

Do you have a box or a graph that does this?
