π Creating HTML Tables
Tables are a good way to organize tabular data on a page. Things like menus, budgets and schedules. just about anything that would look right in a spreadsheet will work in a table. Tables are made up of small boxes called cells. These cells are organized into like-sized columns and rows and have specific HTML code to produce them.
