couldn't you find this question? i answered it twice in the last few days. Anyway, you have 3 th tags:

1. <th>famous monsters by birth year</th>
2. <th>famous monsters</th>
3. <th>birth year</th>

you added your em tags to 1 (famous monster by birth year) you should have added them to famous monster and birth year (2 and 3)
