[Zope] ZPT - handling empty table cells with  

[David Pratt]

Probably a pretty simple question.  The following gives me an 
  in my output which is probably what I am telling it to do.  
I want a simple   so that my empty td's have contents when there 
is nothing in them and my tables will behave in IE.

<td tal:define="option_description option/description">	
	<span tal:condition="python:option_description == ''" 
tal:content="string: &nbsp;" tal:omit-tag="">
		&nbsp;
	</span>
	<span tal:condition="python:option_description != ''" 
tal:content="option_description" tal:omit-tag="">
		Description goes here.
	</span>
</td>

Can someone advise me what I should be substituting in the string to 
provide the desired output.  Also, is there a better way of handling 
empty table cells than a separate set of condition statements for each 
td that may be empty?
