how to add JScrollPane in JTable

:confused: How to add JScrollPane in JTable , and use GridBagLayout to set the JScrollpane in the right side of the JTable.

U can pass the object of JTable into the constructor of JScrollPane,,

code will look something like .

Code:

---


DefaultTableModel tablemodel = new DefaultTableModel(); // to get default tablemodel

tablemodel.addColumn(); // u can add colums,

JTable table = new JTable(tablemodel); // create table

table.setRowHeight(); //set rowheights

JScrollPane scroll = new JScrollPane(table); // add scrollpane

---

see documentation.. for more..

DefaultTableModel tablemodel = new DefaultTableModel(); // to get default tablemodel

tablemodel.addColumn(); // u can add colums,

JTable table = new JTable(tablemodel); // create table

table.setRowHeight(); //set rowheights

JScrollPane scroll = new JScrollPane(table); // add scrollpane

**************
but if i use GridBagLayout the JScrollpane appear in the right side of the table but the table is not scroll when i try to scroll it, also when i add more data in the table the table get resized.

lets debug ur code .. post ur efforts here

ok , so what have i missed in that, and why the scroll is not working.

here is a small example code for the proper working of scrollPane with demo rows and colums. hope u can debug ur code with help of these. Run it and see.
