Sams Teach Yourself HTML 4 in 24 Hours

By Dick Oliver

Summary

In this hour you learned to arrange text and images into organized arrangements or rows and columns, called tables. You learned the three basic tags for creating tables and many optional attributes for controlling the alignment, spacing, and appearance of tables. You also saw that tables can be used together and nested within one another for an even wider variety of layout options.

Table 15.1 summarizes the tags and attributes covered in this hour.
