how to filter the resulted table in dbeaver? I have big sqlite table that I filtered one column with IN statement from the GUI. It worked will but I want to filter another second column also based on the first selected. eg full table looks like.

A    v
A    c
A    n
B    o
B    i
B    k
C    l
C    a
C    z


after first query

A    v
A    c
A    n
C    l
C    a
C    z


I want to filter this second column only (without the o, i, k available in selection menu). 
I found the  best solution is the CREATE TABLE, name it, then use it. 

However, I don't know where this table is saved. I can't find it in the explorer however it is there when I SELECT it. 

What would you do if you have to do that?
You can filter on multiple columns with DBeaver, either on tables or query results.

The menu is called "Custom filter" and is located at the top right of the query result:



From there you can specify custom filters as you need:
