WHEN I FILL ONE ROW, I WANT ANOTHER ROW TO AUTOMATICALLY FILL WITH 1, then 2, then 3, etc.

So I have a table, and when I fill out one column,

I would like the column to the left of it to automatically show a number

starting with 1, then 2, then 3, then 4, etc.

so every time I fill a row in that one column,

the column to the left will automatically show the number of that row that was filled

So Row one column one will say 1 when I fill out Row one column two.

Row two Column one will say 2 when I fill out Row two column two.

Row three column one will say 3 when I fill out Row three column two.
