Save it as table1.html in some folder somewhere. Go ahead and give it its own folder because we will be putting other things in there too. This way you can create your pages and almost instantaneously see the results of your handiwork. Type in your table tags.
Every table needs at least one row.
And of course every row has to have at least one table data cell . I am going to start writing only what is in the table tags. I will leave out the head, body, title, etc. Needless to say, leave them in your document. Now you need something to put in that cell.
