Place the following in the TD tag for the post. Depending upon what your postbits template looks like you may need to place it in several table cells.

<if condition="$post['postcount'] % 2 == 0">class="alt2"<else />class="alt1"</if>

Hope that helps.

In my template it looks likethis for the first table cell

<td <if condition="$post['postcount'] % 2 == 0">class="alt2"<else />class="alt1"</if> style="padding:$stylevar[cellpadding]" width="120" nowrap="nowrap" rowspan="2" $scrolltothis>

I also had to add the conditional to 3 other table cells in my highly customized postbits template.

If you want to post your posbits template or indicate which default template you're using I can show you specifically where to add the conditional.
