Hanging indents will also work inside table cells provided you do something like this:
Code:
<td><p class="hanging-indent">your text here</p></td>
I'm sure if your prepared to be incredibly dirty you might be able to get this to work for you.
make sure you offset your negative indent with an equal padding-left (note: NOT margin-left as kindle just seems to add the two numbers together and you end up with a mess).
