Description

I have an Array(Tuple) field in my table. When I view it in DBeaver, the Tuple fields display correctly, but in CloudBeaver they appear as strings.

Steps to reproduce

Create table

CREATE TABLE my_table
(
    Field Array(Tuple(
        Field1 String,
        Field2 Int64
    ))
)
ENGINE = MergeTree()
ORDER BY tuple();

Add some data

INSERT INTO my_table (Field)
VALUES
([
    ('a', 10),
    ('b', 20),
    ('c', 30)
]),
([
    ('x', 100),
    ('y', 200)
]);

View data:

SELECT * FROM my_table

Cloudbeaver view shows tuples as string

Dbeaver view shows tuples as object:

Expected/Desired Behavior

Dbeaver view should be desired behaviour

CloudBeaver Version

latest

Additional context

Clickhouse version: 25.8.11.66

Hello @senabd

That is it. Because DBeaver supports showing complex data, but CloudBeaver does not.
So, I will consider your ticket as a Feature request.
