First, please note that PgAdmin4 is just an interface to PostgreSQL,
so it is very helpful if you state the actual version of PostgreSQL and O/S you are
working with.
IE: SELECT version();

What you are trying to do can only be done with a SQL statement (IE: Query Tool) So you need to specify the actual columns and order you will be providing.
EG: CREATE TABLE many_col ( a integer, b varchar(10), c text, d varchar(5), e integer, f text, CONSTRAINT many_col PRIMARY KEY (a) );
INSERT INTO many_col ( b, c, a, e) VALUES ('first b', 'first text value', 1, 11), )'secon b', 'first text value', 2, 22);

I am quite new to PostgreSQL and I am having difficulty with the following:
I am trying to input a csv file into a table that has a very large number of
columns. This means that it is impractical to create a table and specify the
name of all the columns. Can the column headings be taken from the first
line of the csv file?
Additionally, I have tried to do this with smaller number of columns with
CREATE table but the column headings appear in a different order to what is
in the csv file (that cannot be edited). I then cannot edit (cut and paste
as you would expect!) the SQL to change the order of the columns. Surely
there must be a way of doing this!! I have no control over the input csv
