The result seem to be fine but the compiler say:Surround ‘Famous Monster’ with tags!.

<body>
    
    <table style="border-collapse:collapse;">
        <thead>
            <tr>

you got 3 th tags, first one famous monsters by birth year:

<th colspan="2" style="color:red">Famous Monsters by Birth Year</th>

and you got famous monsters and birth year:

<th style="padding:5px;">Famous Monster</th>
<th style="padding:5px;border-left:1px solid black;">Birth Year</th>

you should add the em tags to famous monsters and birth year (the “sub”-title), not famous monster by birth year
