How to set cell style in asp: DataGrid?

How can I set the style (css) of a cell in asp:DataGrid?

What am I really trying to achieve? html tablewhere I control the html content for each cell and the css style for each row and for each cell:

<TABLE>
   <TR class="odd available">
      <TD class="holiday available hassub firstColumn">
          <P ...>...
      <TD class="blackout">
          <A href="...">...</A>
      <TD style="available">
          <SPAN ...>...</SPAN>
      <TD class="booked">
          <DIV ...>...</DIV>
      <TD class="orphan available">
          <DIV ...>...</DIV>
      <TD style="orphan booked checked">
          <SPAN ...>...</SPAN>
          <A href="...">...</A>
          <DIV ...>...</DIV>
   </TR>
   <TR class="blackout">
      <TD>34 points
      <TD><%# GetHtmlForCell() %>
   </TR>
</TABLE>

And it is accepted that a asp:Repeatercannot work in this case.

I have HTML that I need to create; and I just need to find out if ASP.net can generate the required html. I guess not, because "WebForms" means you are not generating HTML.
