Try something like this:
1. Drop a Table. By default it has three columns.
2. Drop a button inside the third column. Set its id property to buttonInColumn3, and set its rendered property to false.
3. Drop another button, this time outside the table. Set its id property to buttonOutsideTable.
4. Double-click the buttonOutsideTable and make the method look as follows:
public String buttonOutsideTable_action() {
//switch the first two columns
List cols = tableRowGroup1.getChildren();
Object col = cols.remove(0);
cols.add(1, col);
//toggle between showing staticText3 and buttonInColumn3 (in the third column)
staticText3.setRendered(!staticText3.isRendered());
buttonInColumn3.setRendered(!buttonInColumn3.isRendered());
return null;
5. Run the application and click the button outside the table several times.
