How to import a csv

Hi, I am trying to import a file into a table.

The file has the form
integer, string
integer, string

Table has 5 columns, but I just need to fill the first two, the others can remain blank

I've tried COPY table1 FROM 'C:\\file.txt'

But PGAdmin ||| complains
with the following :
ERROR: invalid input syntax for integer: " 319613 , Sapo "
SQL state: 22P02

319613 , Sapo is the very first line of the file.
It seems that it is trying to put the pair (integer, string) in the first column alone

How can I fix this?

Thanx in advance for your help

Best,
Oliveiros
