how can join two tables based on specific values with repetitions?

I want to join the two table attached based on all the values in the column called 'idstop' of the table T_equo. How can i do?

I wrote this code but it give me this error: "Error using tabular/join (line 130) Unrecognized variable name 'idstop'."

join(T_equo, T_schmidt, 'Keys', {'idstop'})

Tnks in advance

If you give only a single 'Keys' parameter, then the variable name you give must exist in both tables. Here idstop exists only in T_equo, hence the error.

If you want to join two tables based on key columns with different names, you need to specify them using the 'LeftKeys' and 'RightKeys' parameters.
