Basically what I want to do is get a table, which is inside of a TD (don't ask -- I've tried the rowspan setup and it doesn't like to work for this purpose), to span the entire height of the TD. Here's what I've got so far (color-coded to visualize the elements).
The table doesn't want to stretch to fill the available height. Any ideas why?
If the height of the <td> is fixed, try setting style="height:100%" on the table.
As a friendly suggestion— the code you posted is rather inconsistent, mixing HTML attributes and inline CSS, single quotes vs double quotes vs no quotes, using the non-standard <nobr> tag while omitting standard ones like <tbody>. Overall, this can make things rather difficult to debug, especially since an unbalanced tag or even a missing character can "break" a page badly. I would recommend choosing and sticking to a coding style suitable for the DOCTYPE you're using (and I hope I do not presume too much to presume you have set a proper DOCTYPE).
