Table API improvement

Vaadin 6 / 7 / 8 Framework UI
1

Vaadin’s Table - is a excellent component.
And it has excellent method
formatPropertyValue

I think it is good idea to add


private Map<Object, PropertyFormatter> formatters = Collections.emptyMap();
+getter/setter

and this logic to formatPropertyValue (not tested):


protected String formatPropertyValue(Object rowId, Object colId, Property property) {
  if (property == null) {
    return "";
  }

  PropertyFormatter propertyFormatter = formatters.get(colId);
  if (propertyFormatter != null) {
    propertyFormatter.setPropertyDataSource(property);
    String fmt = propertyFormatter.toString();
    propertyFormatter.setPropertyDataSource(null);
    return fmt;
  }

  return property.toString();
}

Then one will need to override formatPropertyValue in rare cases and can reuse battery of PropertyFormatters:
DoublePropertyFormatter, DateTimePropertyFormatter, etc.
