I am using netbeans. I took JTable 'tblSearch' by drag and drop and done below coding

private String rows[][] = new String[0][5];
    private String columns[] = {"Doctor ID","Doctor Name","Address","Contact Number","E-mail Id"};
    private javax.swing.table.DefaultTableModel tm = new javax.swing.table.DefaultTableModel(rows,columns);

tblSearch.setModel(tm);

The code from your example is not working for my code. Please suggest solution for my code.

You need to do
private javax.swing.table.DefaultTableModel tm = new javax.swing.table.DefaultTableModel(rows,columns) {
    public boolean isCellEditable(int row, int col) {
        return false
    }
};

see the example here
http://www.exampledepot.com/egs/javax.swing.table/NoEdit.html

to just make say solumn 1 not editable you could do something like this:


TableModel model = new DefaultTableModel() {
    public boolean isCellEditable(int rowIndex, int mColIndex) {
        return mColIndex!=1;
    }
};

Hi CEHL, I am not geting how to return true/false for the appropriate cell for my code. I want to set all table non editable except some cells. Please suggest solution for my code.

Hi objects, Actually your code works for single column but what if I want to set it for multiple columns.

Actually my 1 table want all cells non editable except some cells And my another table want all cells non editable except some columns.

'Some' needs to be specified numerically. Let's say you need to set the first, third and fifth columns editable, the rest not:
TableModel model = new DefaultTableModel() {
	public boolean isCellEditable(int rowIndex, int mColIndex) {
	    boolean result = false;
	    switch(rowIndex) {
		case 0:
		case 2:
		case 4:
		    result = true;
		default:
		    result = false;
	    }
	    return result;
	}
    };

> Hi objects, Actually your code works for single column but what if I want to set it for multiple columns.

just expand on what I posted above

eg. to only allow editting on columns 2 and 3

        return mColIndex==2 || mColIndex==3;

just change the condition to meet your needs

explained that in my previous comment
you would use

        return (mColIndex==2 && rowIndex=3) || (mColIndex==5 && mRowIndex=8);
