I have got rid of the bug in ur code. The following code should compile.
KRR

import java.awt.*; import java.awt.event.*; import javax.swing.*; import javax.swing.table.*; import java.util.*; class guidemo extends JFrame { private JTable data_tab; private JLabel ptitle; private Container c; private Vector vdata; private Vector vcolname; public guidemo() { super("EST Project Demo"); DefaultTableModel dtm; c=getContentPane(); c.setLayout(null); //c.setSize(500,500);//intialising the contentpane ptitle=new JLabel("EST project Details"); ptitle.setBounds(60,30,150,40); c.add(ptitle); setTableData();//intialising the vectors with some data dtm=new DefaultTableModel(vdata,vcolname); data_tab=new JTable(dtm);//setting table model //data_tab.setPreferredScrollableViewportSize(new Dimension(500, 100)); data_tab.setBounds(160,130,450,250); c.add(data_tab); WindowListener wndCloser = new WindowAdapter(){ public void windowClosing(WindowEvent e) { System.exit(0); } }; addWindowListener(wndCloser); setSize(700,300); setVisible(true); show(); } public static void main(String[] args) { System.out.println("Hello World!"); setDefaultLookAndFeelDecorated(true); new guidemo(); } public void setTableData() { //intialise vectors with some data vdata=new Vector(); vcolname=new Vector(); vdata.removeAllElements(); vdata.addElement(dat("Eliuh",90,900,"uy89")); vdata.addElement(dat("Eryuh",920,900,"uy89")); vdata.addElement(dat("Elddh",940,900,"uy89")); vdata.addElement(dat("Elideu",90,900,"uy89")); vdata.addElement(dat("Elwciuh",760,900,"uy89")); vdata.addElement(dat("Elhhiuh",90,900,"uy89")); vdata.addElement(dat("Elicuh",100,900,"uy89")); vdata.addElement(dat("Eliuech",90,900,"uy89")); vcolname.addElement(cname("NAME","QStart","Qend","PID")); } public Vector dat(String n,int v,int v1,String g) { Vector row = new Vector(); row.addElement(n); row.addElement(new Integer(v)); row.addElement(new Integer(v1)); row.addElement(g); return row; } public Vector cname(String q, String w, String t, String y) { Vector row = new Vector(); row.addElement(q); row.addElement(w); row.addElement(t); row.addElement(y); return row; } }

It would be *a lot* easier just to put a string above the table headers...
is there any really special reason to put it below the headers?

Thanks for ur response. Yes, a JLabel would just suffice in ur case.
But I need to display an info like " No records are available for this
table" when there are no rows. Now, again I can do a setPreferredViewPortSize() of the JTable and add a JLabel under the JTable.
But I have atleast 50 tables in my code. And I dont want to goto every place and add those lines of code. Instead I want to generalize and put
my string info in my "generalized" MyJTable or MyHeaderCellRenderer,etc
(which extends JTable, TableCellRenderer,etc)
well, after some googling, I was able to get some hint. Can someone ,now, have a look into it and help me out.
This one is for cell spanning:

This one can be referred for placing the String in Header ( I prefer it to be here)

Hoping for a reply (suggestion/code snippet) from JGurus!. Thanks.

use TableModel. A table gets its data from an object that implements the TableModel interface.

Can somebody give me an idea of how to go about creating a table like shown below:
_______________________________________________
| column1 | column2 | column 3| Column4 |
_______________________________________________
| **** This row has some string info in it ***|
________________________________________________
| value1 | value2 | value3 | value4 |
________________________________________________
| valuei | value j | valuek | valuez |
_________________________________________________

I need to add that line of text in between the header and the content.
How to go about it ? Should that line be a part of JTableHeader or
should I need to span over the cells of the content ?

I have a JTable whose values gets filled only dynamically.
At times, when the table is empty, I want to show a message like
"no records found" just under the table header.
Just like how in windows machine, when you make a search and if it doesnt
return any records, it prints "Search is complete. There are no results to display"
(stretching many columns) under the table header. I considered using JLabel
(as shown below) but there is always some space b/w the two components.
Let me know ur suggestions. Until then, lemme try out other Layout managers.
Just a code snippet:
class MyTable extends JFrame { private JPanel topPanel; private JTable table; private JScrollPane scrollPane; public MyTable() { setSize( 300, 150 ); topPanel = new JPanel(); topPanel.setLayout( new BorderLayout() ); getContentPane().add( topPanel ); String columnNames[] = { "Column 1", "Column 2", "Column 3" }; String dataValues[][] = {}; table = new JTable( dataValues, columnNames ); scrollPane = new JScrollPane( table ); topPanel.add( scrollPane, BorderLayout.CENTER ); topPanel.add(new Label("No records available"),BorderLayout.SOUTH); } public static void main( String args[] ) { MyTable t = new MyTable(); t.setVisible( true ); } }
