import java.awt.*;  import javax.swing.*; import javax.swing.plaf.basic.basicborders.marginborder; import javax.swing.plaf.metal.metalborders.tableheaderborder; import javax.swing.table.*; import javax.swing.border.*;  public class tablerowrenderingtip extends jpanel {     static object[] columnnames = {"allowed commands", "description"};     private final static dimension scrollpanedimenssion = new dimension(70, 200);     public tablerowrenderingtip()     {                object[][] data =         {             {"one",  "allow proxies act tunnels allow proxies act tunnels allow proxies act tunnels for"},             {"two",  "allow proxies act tunnels allow proxies act tunnels allow proxies act tunnels for"},             {"three","allow proxies act tunnels allow proxies act tunnels allow proxies act tunnels for" },             {"four", "allow proxies act tunnels allow proxies act tunnels allow proxies act tunnels for"},          };               defaulttablemodel model = new defaulttablemodel(data, columnnames);              add( createdata(model) );     }        private static jcomponent createdata(final defaulttablemodel model)      {                jtable inlinetable = new jtable( model );          inlinetable.setshowgrid(false);         inlinetable.setshowverticallines(false);          inlinetable.getcolumn(columnnames[0]).setmaxwidth(130);         inlinetable.getcolumn(columnnames[0]).setminwidth(130);         inlinetable.getcolumn(columnnames[0]).setresizable(false);         inlinetable.getcolumn(columnnames[1]).setminwidth(270);         inlinetable.setautoresizemode(jtable.auto_resize_last_column);          jscrollpane scrollpane = new jscrollpane(inlinetable);         scrollpane.setminimumsize(scrollpanedimenssion);         scrollpane.sethorizontalscrollbarpolicy(scrollpaneconstants.horizontal_scrollbar_as_needed);         return scrollpane;      }      public static void main(string[] args)     {         swingutilities.invokelater(new runnable() {             @override             public void run() {                 createandshowgui();             }         });     }      public static void createandshowgui()     {         jframe.setdefaultlookandfeeldecorated(true);         jframe frame = new jframe();         frame.setdefaultcloseoperation(jframe.exit_on_close);                frame.add( new tablerowrenderingtip() );         frame.pack();         frame.setlocationrelativeto(null);         frame.setvisible(true);     } } 

================================================== scrollpane size fixed: want see data in 2nd column using horizontal scroll bar
