How can I get the content of the last column of another table?

[tx3nn]

I have an application designed for the quota management of a gym. I make a filter [End DateTime]>=TODAY() to know which quotas are active. But I would like to have a view that shows the quotas that are expired and do not have an active quota. I have thought about getting the last cell created in "End DateTime" but I can't get it to work.

How can I do it? I have tried to do a MAXROW but it shows the last date of "End DateTime" of all the users not only of the one in the tab.

In case I have not explained myself I will try to summarize it. I want to have a column that stores the date of the last bookings quota of each client in the Spaces tab (which is the tab table). I could also use a filter. Thanks in advance

I have two tables with the following columns:

Table: Spaces

Columns:
ID - Number
Space - Text
Bookings - List - REF_ROWS("Bookings", "Space")

Table: Bookings

Columns:
Booking ID - Number
Space - Ref Spaces
Start DateTime - Date
End DateTime - Date

You can't just add custom things into the filter toolbar, it only displays columns from that table that are visible and marked as searchable.
