Table formatting in html

Question

How do I centralize the text in the cells of a table. I mean I learned how to centralize the entire table altogether. Please check my code called "Table edited 2017/04/30 17:26" and you shall see that I was able to centralize the entire table altogether. But what I am looking for is to centralize the text alone, inside each cell. Plz help. And thx in advance.
Kudos!
