Demonstrates usage of the ComboBoxCellEditor in JFace-Viewers

Snippet029VirtualTableViewer

Demonstrates usage of JFace-Viewers in virtual mode with an ordinary content provider (often the bottel neck is not the model but the UI). Using this Virtual viewers in conjunction with an ordinary content provider has the advantage that Sorting and Filtering is supported in 3.3.
