Are you sure this works? I only see one quote.

Having said that, the amount of elements you get in @a depends on the number of lines your command returns. Each line becomes a separate element. However, if you do

print "<tr><td>@a<td><tr>";

then you will get a single HTML table cell, no matter how many elements you have in your array - unless of course the array (or $") contains "<td>".
