Examples of org.eclipse.jface.layout.TableColumnLayout

org.eclipse.jface.layout.TableColumnLayout
The TableColumnLayout is the {@link Layout} used to maintain{@link TableColumn} sizes in a {@link Table}.
You can only add the {@link Layout} to a container whose only childis the {@link Table} control you want the {@link Layout} applied to. Don'tassign the layout directly the {@link Table}
