You will need to create a subclass of the TableDecorator
and override the startRow() method:
//This keeps a reference to the previous row object so we can compare the
//current row's sector to the previous row
private Object prevRowObject = null;
//Adds a header row if we are beginning a new sector
public String startRow() {
ItemEntity last;
ItemEntity curr = (ItemEntity)this.getCurrentRowObject();
String header = "";
//Cast the previous item to correct type
if (null == prevRowObject) {
last = new ItemEntity();
} else {
last = (ItemEntity)prevRowObject;
}
// Compare the current sector to the previous sector
// If they are different then insert a header row
if (!last.getSector().equals(curr.getSector())) {
header = "<tr><td colspan=\"10\" class=\"sectorhead\">City Name: " + curr.getSector() + "</td></tr>";
}
}
//Save the current object for the next iteration
prevRowObject = this.getCurrentRowObject();
return header;
}
Then you can add the decorator attribute to the <display:table> tag to tell
it to use your decorator.
Hope that helps you
