Hi there,
I'd like to remove a TableColumn from a Table but i didn't find any way to
do this properly.

In my case the Table is in a Editor Part of the Eclipse Workbench.

When i tried to "dispose" the column directly, column diseapear from the
TableViewer, but when closing the workbench i've got the following error :

Unhandled exception caught in event loop.
Reason:
java.lang.NullPointerException
java.lang.NullPointerException
at org.eclipse.swt.widgets.Table.releaseWidget(Table.java:1091)
at org.eclipse.swt.widgets.Widget.releaseResources(Widget.java: 715)
at org.eclipse.swt.widgets.Composite.releaseChildren(Composite. java:319)
at org.eclipse.swt.widgets.Composite.releaseWidget(Composite.ja va:367)
at org.eclipse.swt.widgets.Widget.releaseResources(Widget.java: 715)

and so on....
i'm running under ibm jdk.1.4.1 and Eclipse 2.1

TableColumn.dispose() is the right answer. Looks like a flavour of
