Adicionando componentes SWT nas células de uma tabela

Adicionando componentes SWT nas células de uma tabela

Algumas vezes é preciso utilizar componentes SWT dentro das células de uma tabela, e isto pode ser feito através de org.eclipse.swt.custom.TableEditor.

Exemplo

A seguir está o código da imagem apresentada onde são adicionados CheckBox e ComboBox dentro de células de uma tabela.

Código de implementação
