Basics of tables in a posting

Hi, I’m new to this. I’m more an author than a tech guy, only used to using Excel/Quattro/Word/WordPerfect. (WordPerfect, the original “WP”). I know nothing about HTML or Dreamweaver or FrontPage, but I’m thinking I might have learn.

All I want to do is add table structure for my postings. For instance, I might have a list of 120 companies’ names, and it sure would be easier to read if I put them in 4 columns of 30 instead of one long list.

Anyone know of links to “tables for beginners” instructions? Thanks.
