Function (org-table--align-field) in org-table.el sandwiches 
text by org-table-separator-space as shown below.

    (concat org-table-separator-space
 	    prefix
 	    field
 	    suffix
-	    org-table-separator-space)))
+	    (propertize org-table-separator-space 'display '(space :relative-width 1.001)))))

I confirmed that this modification works good.
