The <COL> and <COLGROUP> Elements The <COL> and <COLGROUP> elements create and group columns together. Although the in-depth HTML for these elements is beyond the scope of this book, you can see an example using the <COL> and <COLGROUP> elements in Listing 14.10, where I've created a few columns with the <COL> element and grouped them together with the <COLGROUP> element. You can find the properties of these elements in Table 14.19. JavaScript's core HTML properties, methods , and events, which we covered in Chapters 5 and 6, also apply to these elements as well.
