Aligning Table Data - Top

It seems simple enough, but, everthing I try, comes out Centered, sigh.. any help? basically, the data always ends up in the middle, can it be aligned to the top, like in an excel cell??

Here's my table, well, at least the first table row.

<b>Class of Construction</b><P>

<table width="100%" border="1" cellspacing="1" cellpadding="1">
     <tr>
       <td>
         Class
       </td>
     
       <td>
         Description
       </td>

       <td>
         Frame
       </td>

       <td>
         Floor
       </td>

       <td>
         Roof
       </td>

       <td>
         Walls
       </td>
     </tr>        

     <tr>
       <td>
         A          
       </td>

       <td>
               Class A buildings have fireproofed structural steel frames with reinforced          

          concrete or masonry floors and roofs.<P>

              These are typically high-rise or heavy industrial type buildings. (Offices,      

            Hotels, Apartment & Condos)
        </td>

       <td>
              Structural steel columns and beams, fireproofed with masonry, concrete
              plaster, or other non-combustible material
       </td>

       <td>
              Concrete or concrete on steel deck foreproofed.
       </td>

       <td>
              Formed concrete, pre-cast slabs, concrete or gypsum on steel deck,                  

     fireproofed.
       </td>

       <td>
          Nonbearing curtain walls, masonry, concrete, metal and glass panels, stone, steel

          studs and masonry, tile or stucco, etc.
       </td>
     </tr>

</table>
