Well I came up with one way.
|<!--- loop over and create master list of unique values by creating a temp
structure --->
<cfset masterList = structNew()>
<cfloop collection="#positions#" item="type">
<cfloop list="#structKeyList(positions[type])#" index="item">
<cfset masterList[item] = "">
</cfloop>
</cfloop>
<!--- extract master list --->
<cfset masterList = listSort(structKeyList(masterList),"textNoCase")>
<cfoutput>
<table border="1">
<tr>
<cfloop list="#listSort(structKeyList(positions),'textNoCase')#" index="type">
<th>#type#</th>
</cfloop>
</tr>
<!--- loop over master list to display table of all elements ---->
<cfloop list="#masterList#" index="key">
<tr>
<!--- loop over each of the contributint lists --->
<cfloop collection="#positions#" item="type">
<!--- if the current list has the current item, display item --->
<td><cfif structKeyExists(positions[type],key)>#key#</cfif></td>
</cfloop>
</tr>
</cfloop>
</table>
</cfoutput>
