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);
  }
}
