How To Display Data In 3 Columns By 4 Rows Format

I will be eternally greatful if someone can provide snippet of code,
URL or reference material that shows how to display data in a "n
colums * n rows" format.

I am new to ASP and have looked everywhere that I could, but I have
not found an example where data can be formatted to be displayed in a
3 * 4 foramt, like many of the professional sites would do (actually
rows and columns can be any number of rows and columns) All the
examples that I have seen, show data displayed in a top down format.
