number post in table

Hi in my table, in the first column I have the number of posts, the number is taken from the post ID. Is there a code way to make instead of taking the ID of the post to take a sequential order of numbers? Post1 with Number 1, post2 with Number 2, post3 with number 3 and so on? I would like a list with the numbering always in order, if a post is deleted anyway the alphabetical order already set must remain but with numbering 0001-0002-0003-0004-0005-0006…. Is it possible?
Thank you very much! Simon.
