i have jtable,with row header (on left - painted in pink). how can set border lines between them ?

ive tried setborder method , sets outer border, need space between them - in upper column headers.

how can accomplish ?

edit: this code row headers:

static string[] rowheaders = {         "mc 01", "mc 02", "mc 03", "mc 04", "mc 05",         "mc 06", "mc 07", "mc 08", "mc 09", "mc 10", "mc 11", "mc 12",         "mc 13", "mc 14", "mc 15", "mc 16", "mc 17", "mc 18", "mc 19",         "mc 20", "mc 21", "mc 22", "mc 23", "mc 24", "mc 25", "mc 26",         "nitris 01", "nitris 02", "sound a", "sound b", "sound c" };  jlist rowheader;  // creating row header  listmodel lm = new abstractlistmodel() {        public int getsize()        {         return rowheaders.length;       }        public object getelementat(int index)        {         return rowheaders[index];       }     };      rowheader = new jlist(lm);     rowheader.setfixedcellwidth(80);     rowheader.setfixedcellheight(mytable.getrowheight());     rowheader.setbackground(color.pink);     rowheader.setfont(new font("ariel", 1, 18));  //     rowheader.setborder(new lineborder(color.black, 1));      defaultlistcellrenderer renderer =  (defaultlistcellrenderer)rowheader.getcellrenderer();       renderer.sethorizontalalignment(jlabel.center);      mytablescrollpane.setrowheaderview(rowheader);
