How can I change the coIor of one cell in a JTable

Question

Hello,
I need to change the colours of the cells in a table. The problem is that when I try to change the colour of a one cell the colour of entire column is changed. See the way that I tried to use.
TableCellRenderer cr = table.getCellRenderer(row, col);
if (cr instanceof DefaultTableCellRenderer) {
    ((DefaultTableCellRenderer)cr).setBackground(bgColor);
......Please let me know if you have any suggestion
Thanks a lot
Jan

try this ...
In ur table call this
ColorRenderer cell=new ColorRender();
// for(int i=0;i<table.getModel().getColumnCount();i++){
// TableColumn mod=this.getColumn((this.getModel().getColumnName(i)));
mod.setCellRenderer(cell);
And ur ColorRender calss should override DefaultTableCellRenderer like this
class ColorRenderer extends DefaultTableCellRenderer {
protected int align;
public ColorRenderer(int align) {
this.align=align;
public Component getTableCellRendererComponent(JTable table,
Object value, boolean isSelected, boolean hasFocus, int row,
int column) {
setHorizontalAlignment(align);
super.getTableCellRendererComponent(table, value, isSelected,
hasFocus, row, column);
if(col==4){
setBackground(Color.cyan);
return this;
