      public class FlexTable
      extends HTMLTable

  A flexible table that creates cells on demand. It can be jagged (that is, each row can contain a different number of cells) and individual cells can be set to span multiple rows or columns.

  ### Example

  >     public class FlexTableExample implements EntryPoint {

  >       public void onModuleLoad() {
  >         // Tables have no explicit size -- they resize automatically on demand.
  >         FlexTable t = new FlexTable();

  >         // Put some text at the table's extremes.  This forces the table to be
  >         // 3 by 3.
  >         t.setText(0, 0, "upper-left corner");
  >         t.setText(2, 2, "bottom-right corner");

  >         // Let's put a button in the middle...
  >         t.setWidget(1, 0, new Button("Wide Button"));

  >         // ...and set it's column span so that it takes up the whole row.
  >         t.getFlexCellFormatter().setColSpan(1, 0, 3);

  >         RootPanel.get().add(t);
  >       }
  >     }
