    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);
>       }
>     }
