Thanks, Naftoli -- so are you suggesting a separate template for the
TD and for the TR? bind the TD template, and then concatenate them up
for each row?
nevertheless, I started out with this:
var columns : Set
def buildHeader : NodeSeq = {
<TR>{columns.map{<TD>{_}</TD>}.reduceLeft(_+_)) }</TR>
}
but i couldn't figure out the right incantation, and went for the easy
way out
def buildHeader : NodeSeq = {
val result="<TR>" + (if (columns.isEmpty) "" else columns.map
{"<TD>" + _ + "</TD>"}.reduceLeft(_+_)) + "</TR>"
XML.loadString(result)
}
