Tables columns auto-resize is very slow on Windows

Tables columns auto-resize is very slow on Windows. The column are resized one by one and can take up to seconds when there are a more than one of them.
It seems this behavior occurs only on Windows.

Solution

It seems the problem can be fixed by disabling the table redrawing, packing the columns, then enabling back the redrawing.

    viewer.getControl().setRedraw(false);
        viewer.refresh();


        for (TableColumn col : viewer.getTable().getColumns()) {
            col.pack();
        }

        viewer.getControl().setRedraw(true);
