Tables are used to make data easier to interpret or to just give your document more impact. It isn't very hard, it just takes a while to get the hang of. Usually when you do not use the border attribute the table border will become invisible. This is useful when you want to align text in rows and columns, but don't want a table border around it.
Most table rows contain more than one cell.
Many times, you will need a heading for a column of cells of the first row. You only need use the heading cells when necessary. This allows that cell to span two rows. The HTML document you made will be displayed in your browser. You may wish to change the words within the tags and the tag attributes just to try it out.
