Thread: Change Jtable Row and cell Color

hi
i have a jtable and I want to change the color of any row whose column value is equal to the value I want
i use this code

 
{
 
    public Component prepareRenderer ( TableCellRenderer renderer, int row, int column ){
        String status = (String)jTableAzan.getModel().getValueAt(row, 1);
        System.out.println(status);
        if (jtxtshamsi.getText().equals(status)) {
            setBackground(Color.GREEN);
        }
        Component component = super.prepareRenderer(renderer,row,column);
        //System.out.println("getModel= " + getModel().getValueAt(row,column));
 
        if (getModel().getValueAt(row,column) == null){
            component.setBackground(Color.ORANGE);
        }
        else if (getModel().getValueAt(row,column) != null){
            Object value = getModel().getValueAt(row,column).toString();
            if (isRowSelected(row))
            {
                component.setBackground(new Color(56,105,138));
                component.setForeground(Color.WHITE);
 
                if(value.equals("Friday")){
                    component.setForeground(Color.red);
                }
            }
 
            else if(value.equals("Friday")){
                component.setBackground(Color.ORANGE);
                component.setForeground(Color.red);
 
            }
 
            else{
 
                if (row%2 == 0){
                    component.setBackground(new Color(255, 255, 253));
                    component.setForeground(Color.BLACK);
 
                }
                else {
                    component.setBackground(new Color(208,205,205));
                    component.setForeground(Color.BLACK);
                }
            }
 
        }
        return component;
    }
 
}

But this part of my code does not work

 
 String status = (String)jTableAzan.getModel().getValueAt(row, 1);
        System.out.println(status);
        if (jtxtshamsi.getText().equals(status)) {
            setBackground(Color.GREEN);
        }

part of my code does not work

I don't see that code in the renderer code.

Here is a similar problem: https://www.javaprogrammingforums.co...alue-cell.html

in my code if cell value equals Friday cell background and forgrand color is change and Lines whose row is odd change color
i just need in column 2 if cell value is "1400/01/04" that row background color change to green in this code how i can do that?

Can you make a small, simple, complete program that compiles and executes to show the problem?

thanks but i found solution this is my code now and works
i write my code in here
