[Zope] inelegant repetition of ZPT code

[Wilson, Derek]

How about:
 
<table>
    <span tal:repeat="item here/listItems">
       <span tal:condition="repeat/item/even"><tr bgcolor="white"></span>
       <span tal:condition="repeat/item/odd"><tr bgcolor="lightgray"></span>
                   <td>...</td>
        </tr>
    </span>
</table>

I haven't tested it, but it should work.

	Hi Zopers
	
	Another detail that bugs me: how can I translate the following dtml code
	to zpt. It colours table rows in grey/white alternatively. Is the zpt
	version below the only way? It is clearly very inelegant to repeat code.
	
	
	DTML
	
	...
	<table>
	    <dtml-in listItems>
	        <tr <dtml-if sequence-even>bgcolor="lightgray"</dtml-if>>
	            <td>...</td>
	        </tr>
	    </dtml-in>
	</table>
	
	
	ZPT
	
	...
	<table>
	    <span tal:repeat="item here/listItems">
	        <tr bgcolor="white" tal:condition="repeat/item/even">
	            <td>...</td>
	        </tr>
	        <tr bgcolor="lightgray" tal:condition="repeat/item/odd">
	            <td>...</td>
	        </tr>
	    </span>
	</table>
	
	
	thanks and best wishes
	Andre
