nick meyer kindly reply, while content in address little out of date. run jre 1.7 , didn't works expected can altered work correct. alter made follow

/* * add these code in groupabletableheader */    public void updateui(){ //      setui(this.getui());        tablecellrenderer renderer = getdefaultrenderer();       if (renderer instanceof component) {           swingutilities.updatecomponenttreeui((component)renderer);       }   }  /* * add these code in groupabletableheaderui in 2 places, must know */       if (renderer == null) {           renderer = header.getdefaultrenderer();       }  /* * change getsize method in columngroup  */    public dimension getsize(jtable table) {     component comp = renderer.gettablecellrenderercomponent(         table, getheadervalue(), false, false,-1, -1);     int height = comp.getpreferredsize().height;      int width  = 0;     enumeration en = v.elements();     while (en.hasmoreelements()) {       object obj = en.nextelement();       if (obj instanceof tablecolumn) {         tablecolumn acolumn = (tablecolumn)obj;         width += acolumn.getwidth(); //        width += margin;       } else {         width += ((columngroup)obj).getsize(table).width;       }     }     return new dimension(width, height);   }
