Damians, Thanks for your reply. Your solution would put month, day and
year into a new table. The new table would be nested inside the cell
of the original table. This is not quite what I need. I would like
three columns in the original table.
I have created a new class ListPanel. It is derived from HTMLPanel,
but it does not add <div> </div>.
BTW, I could not get java.util.regex.Pattern to work in GWT, so I
wrote my own replace function.
printNodeStack() helped me to debug the code. I left it in as
comments.
import java.util.Vector;
import com.google.gwt.dom.client.Element;
import com.google.gwt.dom.client.Node;
import com.google.gwt.user.client.ui.HTMLPanel;
public class ListPanel extends HTMLPanel{
Vector<Node> aunts= new Vector<Node>(); // aunts should actually
be auntsOrUncles , but that's too long
public ListPanel(String html) {
super(html);
}
/*
Make the children of ListPanel into aunts/uncles of ListPanel
The parent of ListPanel is just a temporary proxy. Remove it.
