Thread: JTable - multiple lines in a cell AND cells not editable?

I'm not sure why that would be the case. You should probably post an SSCCE (that's a link) that demonstrates what you're talking about. Make sure it's as short as possible while also being runnable and demonstrating the problem.

I m giving u the code which i have written 2 years back for my college project.

This is not exactly using table but calendar is there.

private Color cl;

super();
}


public void setColor(Color cl){
this.cl=cl;
}

public Color getColor(){
return cl;
}

this.blank = blank;
