Yeah, that's been haunting me often in table-based layouts.

If it isn't feasible to put the whole td content in one line,
I usually move the closing TT tag immediately before the element:
<td>
[%- IF 1
%]<img src="foo.jpg">
[%- END %]
</td>

I'm only writing this after all the other suggestions because I've
tried such an approach and found that it occasionally removes
whitespace where I don't want it to be removed:
<p>
Always use the
[%- IF 1 %]
<a href="http://www.template-toolkit.org/";>Template Toolkit</a>
[%- END %]
for template processing.
</p>
You usually want whitespace removed before (most) block-level elements
but only *collapsed* before inline elements like <strong>, <a>, ...
