public abstract class CenteredImageLabelProvider
extends OwnerDrawLabelProvider

A table column with SWT.CENTER and just an image, will not be centered on at least Windows platforms. Work around this issue by custom drawing.

FDI's note: reconsider implementation. It causes the default selection color to be limited to the width of the actual columns, rather than the full table width. See https://bugs.eclipse.org/bugs/show_bug.cgi?id=26045
