Write x for each row which's column value is twice in data table

Hi all,

I have a data table with one data column having numbers stored.
c0 c1 c2
a 1 /
a 1 /
b 2 /
b 2 /
a 3 /

I would like to have a “x” set in column c2 set, when the value in c1 is available twice in the entire data table and only when in c0 is an “a”.

Result:
c0 c1 c2
a 1 x
a 1 x
b 2 /
b 2 /
a 3 /

Can you please help me out with that?

Thank you and kr,
GrKa
