java - Setting Margin / Inset for cells in Tablelayout in Swing -

is there anyway set margin cell in tablelayout (for swing application) insets in gridbaglayout.

i need space between cells in table. 1 solution adding rows or columns needed space.

if solution applicable netbeans, more glad.

there 2 tablelayout managers. clear thoughts' tablelayout , more recent esoteric softwares' tablelayout.

i provide simple example using both managers. put 6 buttons on window , add space between them.

clear thoughts' solution

package com.zetcode;  import info.clearthought.layout.tablelayout; import java.awt.eventqueue; import javax.swing.borderfactory; import javax.swing.jbutton; import javax.swing.jframe; import javax.swing.jpanel;   public class tablelayoutgaps2 extends jframe {      public tablelayoutgaps2() {          initui();          settitle("gaps");         setdefaultcloseoperation(jframe.exit_on_close);         setlocationrelativeto(null);     }      private void initui() {          jpanel base = new jpanel();         base.setborder(             borderfactory.createemptyborder(5, 5, 5, 5)         );          double cols[] = {             tablelayout.preferred,             tablelayout.preferred,             tablelayout.preferred         };          double rows[] = {             tablelayout.preferred,             tablelayout.preferred         };          tablelayout layout = new tablelayout(cols, rows);         layout.sethgap(5);         layout.setvgap(5);          base.setlayout(layout);          base.add(new jbutton("button"), "0, 0");         base.add(new jbutton("button"), "1, 0");         base.add(new jbutton("button"), "2, 0");         base.add(new jbutton("button"), "0, 1");         base.add(new jbutton("button"), "1, 1");         base.add(new jbutton("button"), "2, 1");          add(base);          pack();     }      public static void main(string[] args) {        eventqueue.invokelater(new runnable() {             @override             public void run() {                 tablelayoutgaps2 ex = new tablelayoutgaps2();                 ex.setvisible(true);             }         });     } } 

the gaps added using following methods:

layout.sethgap(5); layout.setvgap(5); 

esoteric softwares's solution

package com.zetcode;  import com.esotericsoftware.tablelayout.swing.table; import java.awt.eventqueue; import javax.swing.jbutton; import javax.swing.jframe;   public class tablelayoutgaps3 extends jframe {      public tablelayoutgaps3() {          initui();          settitle("gaps");         setdefaultcloseoperation(jframe.exit_on_close);         setlocationrelativeto(null);     }      private void initui() {          table table = new table();         getcontentpane().add(table);          table.addcell(new jbutton("button")).pad(5, 5, 2.5f, 2.5f);         table.addcell(new jbutton("button")).pad(5, 2.5f, 2.5f, 2.5f);         table.addcell(new jbutton("button")).pad(5, 2.5f, 2.5f, 5);         table.row();         table.addcell(new jbutton("button")).pad(2.5f, 5, 5, 2.5f);         table.addcell(new jbutton("button")).pad(2.5f, 2.5f, 5, 2.5f);         table.addcell(new jbutton("button")).pad(2.5f, 2.5f, 5, 5);          pack();     }      public static void main(string[] args) {        eventqueue.invokelater(new runnable() {             @override             public void run() {                 tablelayoutgaps3 ex = new tablelayoutgaps3();                 ex.setvisible(true);             }         });     } } 

the gaps between components added gap() method.

however, cannot recommend of these 2 layout managers. instead use 1 of following layout managers:

1. miglayout
2. grouplayout
3. formlayout

they more flexible , powerful. these managers cope way better many challanges of layout management.
