how to set renderer to checkbox on jtable for row?

  1. I set the renderer to the checkbox on jtable using following code

    Object[] ColumnData = {"Sr No","Ward Name","Total voters","Action"};
Object[][] RawData=null;

    // in loop

    model.insertRow(x, new Object[]{ key,ward_name_var,total_vot_var,new Object[]{o}}); model.setValueAt(o,x,3); tblWard.setModel(model);

    Setchk(tblWard,3,checkbox); // by calling this method which contains following

    private void Setchk(JTable jTable1, int i, JCheckBox checkbox) { jTable1.getColumnModel().getColumn(i).setCellRenderer((new CWCheckBoxRenderer())); jTable1.getColumnModel().getColumn(i).setCellEditor(new CheckBoxCellEditor()); }

Blockquote

how can we try it for row to set the checkbox on jtable. thanks in advance.

You can simply override the getCellRenderer method of your JTable to return the desired renderer for a given row. Example:

JTable table = new JTable() {
    TableCellRenderer getCellRenderer(int row, int column) {
        if (row == checkBoxRow)
            return myCheckBoxRenderer;
        else
            return super.getCellRenderer(row, column);
    }
};

If your data is of type Boolean.class, the default render will display a checkbox. To change the checkbox in a particular row, you need a corresponding CellEditor. The default render/editor are used here; custom components are illustrated here.
