java - JTable autoscrolling to bottom -

i have jpanel containing 3 jscrollpanes(each contains jtable) added boxlayout, see 3 tables in page , load data dynamically, code logic same 3 tables , column names , cell rendering different, each tables wanted have auto scrolling bottom of table when new rows added table, first 2 tables work perfect , scrollbar goes bottom of table, last table's scroll bar weird things! use same scrolling method 3 tables first 2 works not work!

any ideas?

i removed column adding code clearity idea;

private jscrollpane fillthirdtable(arraylist<displayvariable> displaylist) {     defaulttablemodel model = new defaulttablemodel();      tooltiptable answer = new tooltiptable(model);              answer.setrowheight(60);     answer.setautoresizemode(jtable.auto_resize_off);     answer.setsize(1300, 400);       defaulttablecellrenderer dtcr = new defaulttablecellrenderer();     dtcr.sethorizontalalignment(swingconstants.center);     answer.getcolumn("display variable id").setcellrenderer(dtcr);      jscrollpane scrollpane = null;     (displayvariable var : displaylist) {          model.addrow(new object[] { id, shown, name, value });         answer.setfillsviewportheight(true);         }       tablecolumn c= answer.getcolumnmodel().getcolumn(3);     c.setcellrenderer(new multilinecellrenderer());      tablecolumn c2= answer.getcolumnmodel().getcolumn(2);     c2.setcellrenderer(new multilinecellrenderer());       scrollpane = new jscrollpane(answer);     scrollpane.setsize(1300, 400);  //here call method     scrolltovisible(answer, (displaylist.size()-1), 1);      return scrollpane;  } 

and method autoscrolling;

public void scrolltovisible(jtable table, int rowindex, int vcolindex) {     if (!(table.getparent() instanceof jviewport)) {         return;     }     jviewport viewport = (jviewport)table.getparent();      // rectangle relative table     // northwest corner of cell (0,0) (0,0).     rectangle rect = table.getcellrect(rowindex, vcolindex, true);      // location of viewport relative table     point pt = viewport.getviewposition();      // translate cell location relative     // view, assuming northwest corner of     // view (0,0)     rect.setlocation(rect.x-pt.x, rect.y-pt.y);      // scroll area view     viewport.scrollrecttovisible(rect); } 

as far know, don't need work on parent. use this:

public void scrolltovisible(jtable table, int rowindex, int vcolindex) {     table.scrollrecttovisible(table.getcellrect(rowindex, vcolindex, true)); } 

i did have issue scrolling sorted using swingutilities.invokelater(), might want try well:

public void scrolltovisible(final jtable table, final int rowindex, final int vcolindex) {     swingutilities.invokelater(new runnable() {         @override         public void run() {             table.scrollrecttovisible(table.getcellrect(rowindex, vcolindex, false));         }     }); }
