Sure. This code is very ugly and is backed by a List with HashMaps
inside, that's why I'm using ExpressionTableColumn instead of a
SimpleTableColumn. I'm now using source/columns, it's a lot easier...
public ITableModel getTableModel() {
ArrayList list = someMethodThatGetsTheList()
if (list == null || list.size() == 0) {
setError("The list is empty");
return null;
}
Set columns = ((HashMap)list.get(0)).keySet();
ITableColumn[] listColumns = new ITableColumn[columns.size()];
Iterator it = columns.iterator();
int i = 0;
while (it.hasNext()) {
String tmp = (String) it.next();
listColumns[i++] = new ExpressionTableColumn(tmp,tmp);
}
return new SimpleTableModel(new SimpleListTableDataModel(list),
new
SimpleTableColumnModel(listColumns));
}
I also found later that you shouldn't return a null TableModel (as I
was doing in this code when the list was empty) because the Table
component complains about it.
Hope it helps.
