How to insert newline in table cell

[Hokwang]

Hi,

I usually use table in superset.

I want to add newline in cell.

For now, I use below code,
(SELECT string_agg(t->>'GroupName', E'\n') FROM jsonb_array_elements(s
(my db is postgresql)

and it shows. This is not right newline.

Is there a way to add newline?
