1. There are now three one-row tables in the page. The first one is interactive. Click the 'show letters' button to see action. Then click the 'reset' button to see the disappearance of letters.
2. The second table is not interactive, but static. I tried to modify the code to make it interactive as the first one, but to no avail. I like to see after clicking the 'show letters' button, the letters of 'FLORIDA' will appear in the cells. And then click 'reset' button will make the letters disappear.
| F | L | O | R | I | D | A |
3. There will be more tables in the page, but after I see how the second one is added, I will modify the code by myself.
