Import database table into wordpress posts table

Hi. I have a datebase with some articles. There are quite a few(1000) and it will take a very long time to add them manually. I want to know a way to import the database table into the wordpress posts table.I tried different exports and imports but no luck. Can anyone help me?
Thank you
