Hi, Mathias.

If i understood, you would need this column to be able to "count" how many matches are if you have a serial number in another column;

and if this serial number is repeated 4 times  - then this other 'count matches' should say "4" automatically?

Sorry to disappoint you, but at this time we do not have a functionality like this.

We do have Conditional Formatting - with this you can set various conditions in cells, but this applies only within one Column;

and we have foreign key column feature - which can be used to pull data from a foreign table ( This is just available for SQL based database tables);

but something like this is not available (yet).

Hi TICTAC,

you have posted this question on a wrong category, this ticket is for  wpDataTables.

It seems you are asking questions about Amelia Booking, which is another Plugin.

Can you please open a new ticket, and select "Pre Purchase Questions for Amelia",

then one of our Agents from the Amelia Support Team are going to answer as quickly as possible?

Thank you.
